NAZÈ Yaël (Groupe d'Astrophysique des Hautes Energies, Universite de Liège) The high-energy view of massive stars
Thanks to the current generation of X-ray observatories (in particular XMM and Chandra), our knowledge of the high-energy properties of massive stars dramatically changed in the last two decades. The increased sensitivity enabled us to detect stellar populations in full, the large number of dedicated monitorings unveiled unexpected variations with rotation or orbital period, and the advent of high-resolution spectroscopy revealed the hot plasma properties in great detail. In this seminar, I propose to review the constraints on stellar physics achieved for single stars, magnetic stars, and binaries.
