München (Germany), 2-5 March ABSTRACT BOOK (as at 22-Feb-2010) TALKS In the order of the Program Tuesday, 2 March TUESDAY, 2 March Contribution Number HOGERHEIJDE, Michiel Leiden Observatory (NL) Status IS-O Forming solar-mass stars: an overview of Young Stellar Objects (Overview) The life story of a star begins already before its formation itself, when the initial conditions of its parental interstellar cloud are set. I will review the properties of the dark molecular clouds from which stars form, follow their contraction and collapse, and present the current observational knowledge of the various stages preceding the star's main- sequence life. I will focus on those aspects that are immediately relevant for the star's main-sequence life, namely how its mass is determined, whether it finds itself part of a multiple system or not, and if it is surrounded by a disk that may lead to a planetary system. While the main emphasis of this review is observational, connections to theoretical work will be made throughout. An outlook to future developments, and especially those involving high-angular resolution observations, will conclude my talk. TUESDAY, 2 March Contribution Number DULLEMOND, Cornelis Max-Planck-Institut für Astronomie, Heidelberg (DE) Status IS Disk structure and evolution (Invited) In this talk I will give an overview of theoretical modeling efforts of the structure and evolution of protoplanetary disks. I will show what the role of dust continuum radiative transfer is and how this determines not only the disk vertical hydrostatic structure, but also the spectral energy distribution of the disk. I will discuss the complexities of the dust inner rim, as well as emission from quantum-heated grains.

  • The Nearby Eclipsing Stellar System Δ Velorum
    The nearby eclipsing stellar system δ Velorum Delta Velorum ( δ Vel) is the second brightest star (m v = 1.96) in the southern constellation Vela, near the border with Carina. The system is known due to its multiplicity and includes at least three identified components. Delta Velorum is among our closest stellar neighbors. The multiple stellar system δ Vel (HD 74956, HIP 41913, GJ 321.3, GJ 9278) contains one of the nearest and brightest eclipsing binaries. The binarity of δ Vel was discovered by S. I. Bailey in 1894 from Arequipa, Peru (and independently by Innes 1895). It has already been known as a quadruple system for many years as IDS 08419- 5420 (Jeffers et al., 1963) The system contains two pairs which are located apart at an angular separation of 69 arcsec. The bright close pair AB is separated by 2". The distant satellite binary system CD has its components of 11m and 13m splitted by 6". In 1978 the primary component A was reported to be a spectroscopic binary (sep. 0”.6) in the Proceeding of the Australian Astronomical observatory (Tango et al., 1979), making the whole system quintuple. This was later confirmed by the Hipparcos satellite (0".736, Perryman et al., 1997). Being composed of two A-type in rapid rotation and one F- type main sequence stars, δ Vel AB is particularly interesting to astrophysicists, because of its close distance to the Sun. With a revised Hipparcos parallax of 40.49 ± 0.39mas (van Leeuwen, 2007), it is just 80.6 light-years away. The outward components A and B have a wide orbit with a 142 year orbital period at an average distance of 49 AU.

  • Fundamentals of Stargazing – Month 2 Worksheet
    Fundamentals of Stargazing – Month 2 Worksheet Project #1: On a clear day, before the Sun goes down, get a feel for the quality of seeing and transparency of the sky. Is there any high haze? Jet contrails? If so, the air is likely humid and not terribly transparent. After the Sun goes down, see if the bright stars twinkle. More twinkling means the air is less steady. Does the amount of twinkling change during the evening? Project #2: If you have not already done so, download the free application Stellarium at www.Stellarium.org. Once it is running on your computer, turn on the “Equatorial Grid” under “Sky and Viewing Options” in the Menu. This is the grid of Right Ascension and Declination as discussed in Science (p. 3-6). Notice how the lines of Right Ascension (in ‘hours’) converge at the celestial pole. Estimate the coordinates (RA and Declination) of a few bright stars. Another good tool to evaluate sky transparency? The Beehive Cluster (M44) in Cancer. If you can see this cluster (assuming light pollution isn’t a big problem in your location), then the sky if fairly transparent. Project #3: Find the following bright stars Castor and Pollux in Gemini (remember, Castor is closer to Capella) Regulus, Algieba, and Denebola in Leo The “asses” in Cancer, Assellus Borealis and Assellus Australis Canopus (alpha Carinae) in the constellation Carina (visible south of 30oN latitude) Alphard in the constellation Hydra Project #4: As in Month 1, trace out the path of the ecliptic from (west-to-east) Taurus, Gemini, Cancer, and Leo.

  • Astronomie Pentru Şcolari
    NICU GOGA CARTE DE ASTRONOMIE Editura REVERS CRAIOVA, 2010 Referent ştiinţific: Prof. univ.dr. Radu Constantinescu Editura Revers ISBN: 978-606-92381-6-5 2 În contextul actual al restructurării învăţământului obligatoriu, precum şi al unei manifeste lipse de interes din partea tinerei generaţii pentru studiul disciplinelor din aria curiculară Ştiinţe, se impune o intensificare a activităţilor de promovare a diferitelor discipline ştiinţifice. Dintre aceste discipline Astronomia ocupă un rol prioritar, având în vedere că ea intermediază tinerilor posibilitatea de a învăţa despre lumea în care trăiesc, de a afla tainele şi legile care guvernează Universul. În plus, anul 2009 a căpătat o co-notaţie specială prin declararea lui de către UNESCO drept „Anul Internaţional al Astronomiei”. În acest context, domnul profesor Nicu Goga ne propune acum o a doua carte cu tematică de Astronomie. După apariţia lucrării Geneza, evoluţia şi sfârşitul Universului, un volum care s+a bucurat de un real succes, apariţia lucrării „Carte de Astronomie” reprezintă un adevărat eveniment editorial, cu atât mai mult cu cât ea constitue în acelaşi timp un material monografic şi un material cu caracter didactic. Cartea este structurată în 13 capitole, trecând în revistă problematica generală a Astronomiei cu puţine elemente de Cosmologie. Cartea îşi propune şi reuşeşte pe deplin să ofere răspunsuri la câteva întrebări fundamentale şi tulburătoare legate de existenţa fiinţei umane şi a dimensiunii cosmice a acestei existenţe, incită la dialog şi la dorinţa de cunoaştere. Consider că, în ansamblul său, cartea poate contribui la îmbunătăţirea educaţiei ştiinţifice a tinerilor elevi şi este deosebit de utilă pentru toţi „actorii” implicaţi în procesul de predare-învăţare: elevi, părinţi, profesori.

  • Constellations
    Your Guide to the CONSTELLATIONS INSTRUCTOR'S HANDBOOK Lowell L. Koontz 2002 ii Preface We Earthlings are far more aware of the surroundings at our feet than we are in the heavens above. The study of observational astronomy and locating someone who has expertise in this field has become a rare find. The ancient civilizations had a keen interest in their skies and used the heavens as a navigational tool and as a form of entertainment associating mythology and stories about the constellations. Constellations were derived from mankind's attempt to bring order to the chaos of stars above them. They also realized the celestial objects of the night sky were beyond the control of mankind and associated the heavens with religion. Observational astronomy and familiarity with the night sky today is limited for the following reasons: • Many people live in cities and metropolitan areas have become so well illuminated that light pollution has become a real problem in observing the night sky. • Typical city lighting prevents one from seeing stars that are of fourth, fifth, sixth magnitude thus only a couple hundred stars will be seen. • Under dark skies this number may be as high as 2,500 stars and many of these dim stars helped form the patterns of the constellations. • Light pollution is accountable for reducing the appeal of the night sky and loss of interest by many young people as the night sky is seldom seen in its full splendor. • People spend less time outside than in the past, particularly at night. • Our culture has developed such a profusion of electronic devices that we find less time to do other endeavors in the great outdoors.
