Description
For the large population of massive stars lying behind dust, among which are the youngests and potentially the most massive of our Galaxy, none of the commonly used wind diagnostics can be applied. As an alternative, a few observable infrared hydrogen lines are strong enough to hold wind diagnostics similarly to Hα. Using current state-of-the-art model atmospheres adapted to near-infrared studies, we investigate the profiles, line forming region and formation mechanisms for three of them as a function of Mdot.

Physical properties and evolution of Massive Stars

This project aims at the searching, observation and analysis of massive stars in nearby galaxies to provide a solid empirical ground to understand their physical properties as a function of those key parameters that gobern their evolution (i.e. mass, spin, metallicity, mass loss, and binary interaction). Massive stars are central objects to
