Massive stars, stellar winds, Be stars, line variability

My research focuses on the study of the variability of Be stars, disk and stellar parameters, their rate of mass loss and the connection with disk formation. To do this, we created the BeSOS website: that contains reduced HR spectra of southern Be stars observed with the PUCHEROS spectrograph. We restrict the star parameters of 71 Be stars using stellar atmosphere modeling. Projected rotation speeds were obtained for all spectra, as well as EW, DPS, V / R in the H-alpha line.
