VLTI/AMBER studies of the atmospheric structure and fundamental parameters of red giant and supergiant stars [PDF]
, 2015 We present recent near-IR interferometric studies of red giant and supergiant stars, which are aimed at obtaining information on the structure of the atmospheric layers and at constraining the fundamental parameters of these objects.

Radial Velocity and Astrometric Evidence for a Close Companion to Betelgeuse
The Astrophysical JournalWe examine a century of radial velocity, visual magnitude, and astrometric observations of the nearest red supergiant, Betelgeuse, in order to reexamine the century-old assertion that Betelgeuse might be a spectroscopic binary.

The impact of mass-loss on the evolution and pre-supernova properties of red supergiants [PDF]
, 2014 The post main-sequence evolution of massive stars is very sensitive to many parameters of the stellar models. Key parameters are the mixing processes, the metallicity, the mass-loss rate and the effect of a close companion.

Atmospheric Dynamics of Red Supergiant Stars
, 2008 Thanks to their high-peak infrared luminosity, red supergiant (RSG) stars are fundamental tracers of galactic structure, efficiently probing regions of high interstellar extinction. To understand their properties is crucial and impacts a broad segment of Astrophysics.In this thesis, the answer to the principal questions about RSGs is addressed with ...
