Wolf-Rayet stellar evolution models with improved treatment of the atmosphere
Thomas Voje, Ana Palacios, Fabrice Martins
Evolutionary models of massive stars are quasi-exclusively computed using an Eddington gray atmosphere. This approximation does not accurately describe the complex physical phenome…
Surface chemical composition of single WNh stars
Fabrice Martins
Wolf-Rayet (WR) stars of the WNh category contain a significant fraction of hydrogen at their surface. They can be hydrogen-burning, very massive stars or stars in a post-main sequ…
Twelve years of spectroscopic monitoring in the Galactic Center: the closest look at S-stars near the black hole
M. Habibi, S. Gillessen, F. Martins +11
We study the young S-stars within a distance of 0.04 pc from the supermassive black hole in the center of our Galaxy. Given how inhospitable the region is for star formation, their…
GCIRS 7, a pulsating M1 supergiant at the Galactic centre. Physical properties and age
T. Paumard, O. Pfuhl, F. Martins +10
The stellar population in the central parsec of the Galaxy is dominated by an old (several Gyr) population, but young, massive stars dominate the luminosity function. We have studi…
Massive Young Stars in the Galactic Center
H. Bartko
We summarize our latest observations of the nuclear star cluster in the central parsec of the Galaxy with the adaptive optics assisted, integral field spectrograph SINFONI on the E…
An Extremely Top-Heavy IMF in the Galactic Center Stellar Disks
H. Bartko, F. Martins, S. Trippe +19
We present new observations of the nuclear star cluster in the central parsec of the Galaxy with the adaptive optics assisted, integral field spectrograph SINFONI on the ESO/VLT. O…
