Le 11 mars 2016 De 10h30 à 12h00 Zakaria Meliani Observatoire de Paris-Meudon Accretion disks play an important role in the evolution of their relativistic inner compact objects. The emergence of a new generation of interferometers will allow resolving these accretion disks...
Le 4 mars 2016 De 10h30 à 12h00 Jean-Baptiste COURBOT ICube - Université de StrasbourgThe Multi-Unit Spectroscopic Explorer (MUSE) instrument, located at the VLT, allows the investigation of a wide spectral range across a 1x1 arcmin sky region. In particular, its spectral...
Le 19 février 2016 De 10h30 à 12h00 Douglas SPOLYAR Stockholm UniversityDark Stars (DS) are stellar objects made (almost entirely) of ordinary atomic material but powered by the heat from Dark Matter (DM) annihilation (rather than by fusion). Weakly Interacting Massive...
Le 12 février 2016 De 10h30 à 12h00 Chatterjee Debarati Laboratoire de physique corpusculaire de Caen Neutron stars are dense compact objects, observable as pulsars by virtue of their strong magnetic fields. Further, X-ray Dim Isolated Neutron Stars (XDINSs) and Rotating...
Le 5 février 2016 De 10h30 à 12h00 Zolotukhin Ivan IRAP Toulouse We compiled a database of all photons registered by the XMM-Newton mission since its launch. To facilitate scientific usage of this valuable data collection we developed a web application on top of it which...
Le 29 janvier 2016 De 10h30 à 12h00 Mirel BIRLAN IMCCE, Observatoire de Paris M4AST (Modelling for asteroids) is a tool devoted to model and interpret spectra data in the visible and near-infrared of asteroids. It is composed by an asteroid spectral database and a set of...
Le 11 décembre 2015 De 10h30 à 12h00 Ulrich BASTIAN ARI, Heidelberg According to the official plan, the first astrometric data releases from Gaia are expected by mid 2016 (positions only) and mid 2017 (incl. parallaxes and proper motions). This is the time needed to collect...
Le 27 novembre 2015 De 10h30 à 12h00 Hervé DOLE Institut d'Astrophysique Spatiale, Orsay Le satellite Planck, pierre angulaire de l’ESA dédiée à la cosmologie et lancé en 2009, a observé la totalité du ciel pendant près de 2 ans et demi, et mesuré le fond diffus...
Le 18 novembre 2015 De 14h00 à 15h00 Anaïs GONNEAU Instituto de Astrofisica de Canarias The X-shooter Spectral Library (XSL) is a state-of-art stellar spectral library, which will be a benchmark library for stellar population studies in the era of James Webb Space Telescope...
Le 13 novembre 2015 De 10h30 à 12h00 Coralie NEINER Observatoire de Paris I will present the latest observational results obtained on the magnetic fields of massive stars thanks mainly to large spectropolarimetric programs. I will discuss the origin of these magnetic fields,...
