A totes elles els dedico aquesta tesi i els estic enormement agraïda. En primer lloc vull agrair als meus pares, Magda i Xavier, per haver-me educat i fet créixer convertint-me en la persona que sóc ara. Ells ho han donat tot perquè jo pogués tirar endavant els meus estudis amb les mínimes preocupacions possibles. Moltes gràcies per haver estat sempre al meu costat celebrant els millors moments i acompanyant-me en les decisions més difícils. Agraeixo especialment al meu pare haver-me iniciat en el món de l’astronomia amateur ja des de petita, que s’ha acabat convertint en la meva passió i professió. També vull agrair al Pau, el meu germà, tots els bons moments que hem passat junts i el seu optimisme crític amb que sempre m’ha aconsellat. Recordo amb especial carinyo les bones rebudes que m’has fet cada vegada que he tornat a casa i sé que sempre puc comptar amb tu. A l’Aleix li agreixo el seu suport incondicional al llarg d’aquests tres anys, haver-me animat a iniciar, seguir i acabar aquesta tesi malgrat que això signi- fiques la distància (i molts viatgets a França). Tu m’has descobert lo Burgà, un lloc on el temps es para, on no hi ha preocupacions, on desconnecto de veritat. Aquest lloc ha estat un salvavides per moments en que m’he sentit totalment desbordada. Sense la teva alegria, coratge i força per tirar endavant, aquesta tesi hauria estat molt més difícil. També agraeixo a la família Benaiges-Lliberia haver-me acollit amb els braços oberts des del primer dia. A la resta de la família els agraeixo l’escalf i amor que sempre m’han donat i l’alegria que els caracteritza. Al meu avi, la persona més alegre que conec, gràcies per regalar-me un somriure cada vegada que ens veiem, per totes les paraules amables i l’hospitalitat que sempre tens pels que et venen a veure. A tu et dedico un dels planetes trobats en aquesta tesi. A la iaia, gràcies per fer-me sentir sempre tant especial i estimada. Gràcies per rebre’m amb els braços oberts cada vegada que torno a casa i per preguntar-me sempre "i quan tornaràs?". A les meves tietes i oncle, Núria, Pep, Montse, Imma, Anna, Jose, Jordi i Salva els agraeixo que m’hagin ensenyat que la família és gent amb la que pots confiar i compartir, per estar sempre disposats a les celebracions o a fer pinya en els moments més baixos. Als meus cosins, Mireia, Raúl, Berta, Aina, Clàudia i Gael els agraeixo tots els bons moments. ix L’altre gran pilar que m’ha mantingut alegre i feliç durant la tesi ha estat l’amistat. Judit i Laura gràcies per haver estat al meu costat tot aquest temps. Valoro especialment que haguem estat capaces de reinventar la nostra amistat malgrat la distància. Gràcies per estimar-me i valorar-me tal com sóc i per escolar-me sempre, perquè després de parlar amb volatres els problemes són menys greus i les alegries més grans. També vull agrair a la resta de la colla: Arnau, Berta, Erik, Ester, Guille, Joan, Sonia, Vera les vostres visites a Bordeus, les bones rebudes a Ribes i totes les festes que hem passat junts. Laia i Anna, us estic molt agaïda per la vostra amistat. A Bordeus, més enllà de mantenir les amistats que ja tenia n’he descobert de noves. Laia, per molt que ja ens coneguéssim a Barcelona, viure experiències semblants a l’estranger m’ha apropat molt a tu. Ser companyes de feina (i de despatx!), compartir tants viatges Burdeus-Barcelona, Barcelona-Bordeus, les classes d’Ukelele, de ioga, les tardes al gym... són innumerables els bons records amb tu! T’estic molt agraïda per l’amistat que m’has regalat tot aquest temps així com els consells i suport en l’àmbit professional. Recordo amb molt d’escalf els caps de setmana i viatges que hem fet amb tu, l’Alfred i l’Aleix. També agraeixo el suport de bons amics del Grau i Màster que m’han acom- panyat la resta del temps. Guillem, ets un gran amic des de que ens vam conèixer. T’agraeixo tantes hores en biblioteques i aules d’estudi i per aportar calma i seny sempre que m’estresso. A la resta de companys del Grau i Màster Pol, Núria, Adrià, Bruno, Borja, Cate, Clara, Gemma, Glòria, Manel i tants altres els agraeixo tot el camí que hem fet junts, tant les hores de classe i estudi, com viatges i quedades que han reforçat la nostra amistat. I would also like to thank Cristina, Giuliano, Laia, May and Silvia because with you I felt I was home. I remember with special affection all the dinners and trips as well as our endless conversations on how to deal with bureaucracy in France. I’m also extremely thankful to you for your help in moving, I can’t imagine how I would have done it without you. Grazie mille a tutti! This thesis would not have been possible without Hervé Bouy, my PhD supervisor. Thank you for giving me the great chance to join your team and pursue this thesis. I am very grateful for all the opportunities you gave me of visiting the most amazing telescopes in the world. I have a warm memory of the nights we spent at the CTIO and in la Palma, those were certainly the best moments of this thesis. I acknowledge you for the freedom you gave me during these three years of thesis and for the variety of topics in which you encouraged me to explore and which remarkably enriched this thesis. I thank Javier Olivares, co-advisor of this thesis, for his patience and kindness while teaching me statistics. I am especially grateful for your wise advise and because you have never had a no for an answer whenever I needed you. I x am extremely grateful to all the COSMIC DANCe team: Hervé, Ángel, David, Javier, Luisma, Maxime, Nuria, Phillip. Each of you has contributed to improve this thesis and I have learned a lot being by your side. I thank Nuria Hélamo for guiding me in the study of discs; Jorge Lillo-Box, David Barrado and Sean Raymond for introducing me in the amazing world of exoplanets; Phillip Galli for his contribution in providing the radial velocities analysed in this thesis; Francesca Figueras for her critical and constructive comments which significantly improved the study on the dynamical ages; Luis Sarro for his wise and kind advise in statistics and Gaia; Wolfgang Brander for helping me obtain the essential spectroscopic observations in FEROS; and Nicolas Lodieu and Koraljka Muži´cfor their help in the reduction and interpretation of spectra of ultracool dwarfs. I am grateful to Ingo Thies for sharing with me his models of the Initial Mass Function, to France Allard and Isabelle Barraffe for providing me with the latest version of the BT-Settl and BHAC15 models and to Ferran Torra for his advice in the proper use of Gaia DR2 data.

Her encouragement, guidance, and perspective helped me navigate many a challenging problem, and my conversations with her were a consistent source of positivity and learning throughout my time at Caltech. I leave graduate school a better scientist and person for having her as a role model. Heather fostered a wonderfully positive and supportive environment for her students, giving us the space to explore and grow - I could not have asked for a better advisor or research experience. I would also like to thank Konstantin Batygin for enthusiastic and illuminating discussions that always left me more excited to explore the result at hand. Thank you as well to Dimitri Mawet for providing both expertise and contagious optimism for some of my latest direct imaging endeavors. Thank you to the rest of my thesis committee, namely Geoff Blake, Evan Kirby, and Chuck Steidel for their support, helpful conversations, and insightful questions. I am grateful to have had the opportunity to collaborate with Brendan Bowler. His talk at Caltech my second year of graduate school introduced me to an unexpected population of massive wide-separation planetary-mass companions, and lead to a long-running collaboration from which several of my thesis projects were born.

Called “Cool Stars, Stellar Systems, and the Sun,” the meeting empha- sized the solar stellar connection and focused discussion on “several topics … in which the similarity is manifest: the structures of chromospheres and coronae, stellar activity, and the phenomena of mass loss,” according to the preface of the resulting, “Special Report of the Smithsonian Astrophysical Observatory.” We could easily have chosen the same topics for this meeting. Over the summer of 1980, the group met again in Bonas, France and then back in Cambridge in 1981. Nearly 40 years on, I am comfortable saying these workshops have evolved to be the premier conference series for cool star research. Cool Stars has been held largely biennially, alternating between North America and Europe. Over that time, the field of stellar astro- physics has been upended several times, first by results from Hubble, then ROSAT, then Keck and other large aperture ground-based adaptive optics telescopes.

  • A Basic Requirement for Studying the Heavens Is Determining Where In
    Abasic requirement for studying the heavens is determining where in the sky things are. To specify sky positions, astronomers have developed several coordinate systems. Each uses a coordinate grid projected on to the celestial sphere, in analogy to the geographic coordinate system used on the surface of the Earth. The coordinate systems differ only in their choice of the fundamental plane, which divides the sky into two equal hemispheres along a great circle (the fundamental plane of the geographic system is the Earth's equator) . Each coordinate system is named for its choice of fundamental plane. The equatorial coordinate system is probably the most widely used celestial coordinate system. It is also the one most closely related to the geographic coordinate system, because they use the same fun­ damental plane and the same poles. The projection of the Earth's equator onto the celestial sphere is called the celestial equator. Similarly, projecting the geographic poles on to the celest ial sphere defines the north and south celestial poles. However, there is an important difference between the equatorial and geographic coordinate systems: the geographic system is fixed to the Earth; it rotates as the Earth does . The equatorial system is fixed to the stars, so it appears to rotate across the sky with the stars, but of course it's really the Earth rotating under the fixed sky. The latitudinal (latitude-like) angle of the equatorial system is called declination (Dec for short) . It measures the angle of an object above or below the celestial equator. The longitud inal angle is called the right ascension (RA for short).

  • Constellation Is the Corona Australis
    CORONA AUSTRALIS, THE SOUTHERN CROWN Corona Australis is a constellation in the southern celestial hemisphere. Its Latin name means "southern crown", and it is the southern counterpart of Corona Borealis, the northern crown. One of the 48 constellations listed by the 2nd-century astronomer Ptolemy, it remains one of the 88 modern constellations. The Ancient Greeks saw Corona Australis as a wreath rather than a crown and associated it with Sagittarius or Centaurus. Other cultures have likened the pattern to a turtle, ostrich nest, a tent, or even a hut belonging to a rock hyrax (a shrewmouse; a small, well-furred, rotund animals with short tails). Although fainter than its northern namesake, the oval - or horseshoe-shaped pattern of its brighter stars renders it distinctive. Alpha and Beta Coronae Australis are its two brightest stars with an apparent magnitude of around 4.1. Epsilon Coronae Australis is the brightest example of a W Ursae Majoris variable in the southern sky (an eclipsing contact binary). Lying alongside the Milky Way, Corona Australis contains one of the closest star-forming regions to our Solar System —a dusty dark nebula known as the Corona Australis Molecular Cloud, lying about 430 light years away. Within it are stars at the earliest stages of their lifespan. The variable stars R and TY Coronae Australis light up parts of the nebula, which varies in brightness accordingly. Corona Australis is bordered by Sagittarius to the north, Scorpius to the west, Telescopium to the south, and Ara to the southwest. The three-letter abbreviation for the constellation, as adopted by the International Astronomical Union in 1922, is 'CrA'.

The Terms of Reference and membership for WG Star Names (WGSN) are provided at the IAU website: https://www.iau.org/science/scientific_bodies/working_groups/280/. ​ ​ ​ WGSN was re-proposed to Division C and was approved in April 2019 as a functional WG whose scope extends beyond the normal 3-year cycle of IAU working groups. The WGSN was specifically called out on p. 22 of IAU Strategic Plan 2020-2030: “The IAU serves as the ​ internationally recognised authority for assigning designations to celestial bodies and their surface features. To do so, the IAU has a number of Working Groups on various topics, most notably on the nomenclature of small bodies in the Solar System and planetary systems under Division F and on Star Names under Division C.” WGSN continues its long term activity of researching cultural astronomy literature for star names, and researching etymologies with the goal of adding this information to the WGSN’s online materials.

  • Accurate Positions of Pluto and Asteroids Observed in Bucharest During the Year 1932
    ACCURATE POSITIONS OF PLUTO AND ASTEROIDS OBSERVED IN BUCHAREST DURING THE YEAR 1932 GHEORGHE BOCŞA, PETRE POPESCU, MIHAELA LICULESCU Astronomical Institute of the Romanian Academy Str. Cuţitul de Argint 5, 040557 Bucharest, Romania E-mail: [email protected] Abstract. The paper contains the observations of minor planets performed in Bucharest Astronomical Observatory in the year 1932 with the 380/6000 mm astrograph. Both Turner’s (constants) and Schlesinger’s (dependences) methods were used in the computation of the normal coordinates of the objects. Keywords: photographic astrometry – minor planets. 1. INTRODUCTION The article is a continuation of the complete investigation of Bucharest Wide-Field Plates Archive initiated in 2010; it contains the plates with asteroids observed in 1932. That year 185 plates were exposed and were stored in the archive, but were not reduced. After analysing them, 98 plates were detected to contain measurable minor planets. The first observed positions in this year were of planet Pluto. They were exposed on 1318cm plates, with 52 minutes exposure .The observations were performed by the famous Romanian astronomer Professor Gheorghe Demetrescu. The most difficult problem was the identification of the planet, the three plates obtained in 1932 having dozens of stars with up to 15 magnitudes. As all the observations were performed in the same month and the planet did not have a great proper motion, it was possible to superpose two plates and to identify Pluto. The values (O–C)α and (O–C)δ were calculated by M. Svechnikov from the Institute of Applied Astronomy in Sankt Petersburg on the basis of precise positions obtained in Bucharest, which we integrated in Pluto’s orbit.

Hydrated minerals have been found mainly on Mars surface, on main belt primitive asteroids and possibly also on few TNOs. These materials have been produced by hydration of pristine anhydrous silicates during the aqueous alteration process, that, to be active, needed the presence of liquid water under low temperature conditions (below 320 K) to chemically alter the minerals.
