The near infrared zodiacal cloud—is of prime importance to characterise the global architecture of planetary photometry allows us to identify stars with IR excesses, and we find that the Class II pop- systems. Because of the high contrast and small angular separation between the star and ulation is very large, around 25% for stars and 40% for brown dwarfs, despite the fact that the exozodiacal light, high-precision infrared interferometry is the best-suited tool to carry the Hα equivalent width is low for a significant fraction of them. In addition, there are a out such observations. In this paper, we review the first detection of an exozodiacal disc by number of substellar objects, classified as Class III, that have optically thin disks. The Class this method recently reported around Vega by Absil et al. (2006), and discuss the currently II members are distributed in an inhomogenous way, lying preferently in a filament running on-going observing efforts in this domain. We show how interferometric data can give access toward the south-east. The IR excesses for the Collinder 69 members range from pure Class to the composition and the dynamics (including LHB-like events) of extrasolar planetary II (flat or nearly flat spectra longward of 1 micron), to transition disks with no near-IR ex- systems, and thereby put useful constraints on the presence of small bodies and/or giant cess but excesses beginning within the IRAC wavelength range, to two stars with excess only planets. This statement is illustrated with new data obtained on various bright Vega-type detected at 24 micron. Collinder 69 thus appears to be at an age where it provides a natural stars, including Vega itself. Finally, we show how the new generation of interferometric laboratory for the study of primordial disks and their dissipation. instruments will change our view of debris discs: with their increased sensitivity and imaging capabilities, they will constrain the morphology of bright exozodiacal discs and push the detection limit towards meaningful density levels in the context of future life-finding missions such as Darwin/TPF. 11 12 Galactic searches for protoplanetary disks around A-type stars Formation conditions of planetesimals in disks and implications for the composition of exoplanets Hales, Antonio (NRAO, USA) Mousis, Olivier (Observatoire de Besan¸con, France) I will present results from a search for dusty early A-type stars in the northern galactic plane.

  • Lurking in the Shadows: Wide-Separation Gas Giants As Tracers of Planet Formation
    Lurking in the Shadows: Wide-Separation Gas Giants as Tracers of Planet Formation Thesis by Marta Levesque Bryan In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy CALIFORNIA INSTITUTE OF TECHNOLOGY Pasadena, California 2018 Defended May 1, 2018 ii © 2018 Marta Levesque Bryan ORCID: [0000-0002-6076-5967] All rights reserved iii ACKNOWLEDGEMENTS First and foremost I would like to thank Heather Knutson, who I had the great privilege of working with as my thesis advisor. 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.

  • A Review on Substellar Objects Below the Deuterium Burning Mass Limit: Planets, Brown Dwarfs Or What?
    geosciences Review A Review on Substellar Objects below the Deuterium Burning Mass Limit: Planets, Brown Dwarfs or What? José A. Caballero Centro de Astrobiología (CSIC-INTA), ESAC, Camino Bajo del Castillo s/n, E-28692 Villanueva de la Cañada, Madrid, Spain; [email protected] Received: 23 August 2018; Accepted: 10 September 2018; Published: 28 September 2018 Abstract: “Free-floating, non-deuterium-burning, substellar objects” are isolated bodies of a few Jupiter masses found in very young open clusters and associations, nearby young moving groups, and in the immediate vicinity of the Sun. They are neither brown dwarfs nor planets. In this paper, their nomenclature, history of discovery, sites of detection, formation mechanisms, and future directions of research are reviewed. Most free-floating, non-deuterium-burning, substellar objects share the same formation mechanism as low-mass stars and brown dwarfs, but there are still a few caveats, such as the value of the opacity mass limit, the minimum mass at which an isolated body can form via turbulent fragmentation from a cloud. The least massive free-floating substellar objects found to date have masses of about 0.004 Msol, but current and future surveys should aim at breaking this record. For that, we may need LSST, Euclid and WFIRST. Keywords: planetary systems; stars: brown dwarfs; stars: low mass; galaxy: solar neighborhood; galaxy: open clusters and associations 1. Introduction I can’t answer why (I’m not a gangstar) But I can tell you how (I’m not a flam star) We were born upside-down (I’m a star’s star) Born the wrong way ’round (I’m not a white star) I’m a blackstar, I’m not a gangstar I’m a blackstar, I’m a blackstar I’m not a pornstar, I’m not a wandering star I’m a blackstar, I’m a blackstar Blackstar, F (2016), David Bowie The tenth star of George van Biesbroeck’s catalogue of high, common, proper motion companions, vB 10, was from the end of the Second World War to the early 1980s, and had an entry on the least massive star known [1–3].

  • Modeling the Spatial Structure of Debris Disks
    MODELING THE SPATIAL STRUCTURE OF DEBRIS DISKS Simultaneous multi-wavelength modeling and predictions on the observability of planet-disk interaction Dissertation zur Erlangung des Doktorgrades der Mathematisch-Naturwissenschaftlichen Fakult¨at der Christian-Albrechts-Universit¨at zu Kiel vorgelegt von Steve Ertel Kiel, 2011 Referent: Prof. Dr. Sebastian Wolf Koreferent: Prof. Dr. Holger Kersten Tag der m¨undlichen Pr¨ufung: 07.02.2012 Zum Druck genehmigt: 07.02.2012 gez. Prof. Dr. Lutz Kipp, Dekan To those who are more important to me than this work Ach! was in tiefer Brust uns da entsprungen, Was sich die Lippe sch¨uchtern vorgelallt, Mißraten jetzt und jetzt vielleicht gelungen, Verschlingt des wilden Augenblicks Gewalt. Oft wenn es erst durch Jahre durchgedrungen Erscheint es in vollendeter Gestalt. Was gl¨anzt ist f¨ur den Augenblick geboren; Das Echte bleibt der Nachwelt unverloren. (Goethe, Faust, Vorspiel auf dem Theater) Abstract The content of the present thesis can be grouped in two main topics: (1) The modeling of the spatial dust distribution in debris disks from available high spatial resolution, high quality data. (2) The modeling of planet-disk interaction in debris disks, the investigation of the observability of this process with present and near future instruments, and the preparation and execution of new observations of debris disks. Debris disks are evolved dust disks (mostly) around main sequence stars. The dust de- tected in such disks must be transient or, more likely, continuously replenished by ongoing collisions of bigger objects like planetesimals left over from the planet formation process. A correlation between the existence of planets and debris disks is expected.

Zusammenfassung Zirkumstellare Scheiben sind eine Folge des Sternentstehungsprozesses. Sie be- stehen aus Gas und Staub und gelten nach dem heutigen Verständnis als die Umgebung für die Entstehung von Planeten. Wie die Staubteilchen in der Größe von wenigen Nanometern zu Objekten von mehreren Metern im Durchmesser anwachsen und sich bis hin zu Planeten entwickeln, ist bislang im Detail noch kaum verstanden und stellt eine fundamentale Frage in der Astrophysik dar. Staubkornwachstum sowie radiale Segregation und vertikale Sedimentation der Staubteilchen innerhalb der Scheibe gehören dabei zu den wichtigsten Prozessen in der Entwicklung zirkumstellarer Scheiben. Für ein besseres Verständnis von der Entstehung von Planeten ist es erforderlich, die beobachtbaren Auswirkun- gen dieser und weiterer Entwicklungsprozesse zu studieren. Im ersten Teil dieser Dissertation wird, basierend auf hochaufgelösten Beobach- tungsdaten im Wellenlängenbereich vom nahen Infrarot bis zu Millimeterwellen- längen, die detaillierte Modellierung der zirkumstellaren Scheibe des Butterfly Stars präsentiert. Das unter Verwendung von Strahlungstransportmethoden ent- wickelte Modell ist dabei in der Lage, alle Beobachtungsergebnisse zu reprodu- zieren und liefert neue Erkenntnisse über die Staubeigenschaften in dieser Schei- be.

  • Why Do Hydrogen and Helium Migrate from Some Planets and Smaller
    Why do Hydrogen and Helium Migrate from Some Planets and Smaller Objects? Author Weitter Duckss Independent Researcher, Zadar, Croatia mail: [email protected] Project: https://www.svemir-ipaksevrti.com/ Abstract This article analyzes the processes through measuring the material incoming from the outer space onto Earth, through migrating of hydrogen and helium from our atmosphere and from other objects and through inability to detect the radioactive effects on stars and objects with melted interiorities. Habitable periods on such objects are determined through the processes. 1. Introduction The goal of the article is to give arguments, based on the existing data bases, that a constant growth of space objects, as well as their rotation and tidal forces, cause their warming up and radiation emissions, therefore making radioactive processes of fission and fusion – which are not detected on stars and other objects anyway – unnecessary. The article gives evidence of hydrogen and helium migrating towards the objects that have more mass and of temperature levels of stars being directly related to their chemical compositions and the objects in their orbits. The argumentation to support a habitable period will be derived from the natural processes of constant growth and matter gathering. 2. Why there is no radioactive emission, derived from the processes of fission and fusion, inside stars? All data bases indicate that astronomic research (or, evidence) support the existence of a constant (monotonous), omnipresent, slow gathering of matter. The processes are "more accelerated" in such part of the Universe where there is more matter gathered (in the form of nebulae, molecular clouds, etc.) during a long period of time, but gathering takes place constantly in the whole volume of the Universe as well.

  • Young Star's Companion Has Only Forty Times the Mass of Jupiter 25 February 2005
    Young Star's Companion Has Only Forty Times the Mass of Jupiter 25 February 2005 this search by observing many nearby young stars in the constellation Taurus with its Coronagraphic imager with Adaptive Optics (CIAO). (See our April 2004 press release for more information on this program and an image of a protoplanetary disk.) CIAO's speciality is observing faint objects near bright objects. CIAO sharpens an image using a technique called adaptive optics, and blocks the light from a bright object using a mask called a coronagraph. The research team targeted young stars since planets and brown dwarfs are brighter when they are young. Planets weigh less than 13 times the mass of Jupiter. Brown dwarfs are 13 to 80 times more massive than Jupiter. Unlike stars like the Sun, brown dwarfs don't have enough mass to generate energy through nuclear fusion. So far, extrasolar planets orbiting around normal stars have been detected only by indirect means, such as observing the wobble in the main star caused by the gravitational tug and pull with the orbiting planet. No direct image of an extrasolar Astronomers have weighed DH Tauri's companion planet around a normal star exists to date.
