Magnetism in massive stars

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,...

Galactic Archaeology to its limits

Le 6 novembre 2015 De 10h30 à 12h00 Else STARKENBURG AIP Potsdam Resolved stellar spectroscopy presents us with "archaeological" evidence about chemical enrichment processes back to the earliest times. In this talk I will review the very early (chemical) evolution of the...

The Optical-Infrared Extinction Curve and its Variation in the Galaxy

Le 30 octobre 2015De 10h30 à 12h00 Eddie SCHLAFLY MPIA Heidelberg The dust extinction curve is an important diagnostic of the physics of the interstellar medium, as well as a critical element to many observational programs. Detailed studies of the extinction curve and...

Binary stars – an interferometric view

Le 16 octobre 2015 De 10h30 à 12h00 Henri BOFFIN ESO, Paranal Most stars are born and live in binary systems, and will often interact in one way or another. The study of binary stars is therefore critical to apprehend many of the most interesting classes of stars. Moreover,...

Galactic Palaeontology

Le 9 octobre 2015 De 10h30 à 12h00 Eline TOLSTOY Kapteyn Astronomical Institute, Groningen  I will talk about how resolved stellar populations in the nearby Local Group dwarf galaxies have been used to study the detailed chemical, kinematic and star formation history of...

The evolution of massive galaxies in different environments

Le 11 septembre 2015 De 10h30 à 12h00 Simona MEI Observatoire de Paris  We will present recent results on the evolution of very massive galaxies in the field and in dense environments (e.g. galaxy clusters), using recent data from the HST/CANDELS and COSMOS surveys. We will...
