Ronny Blomme - Gaia
Royal Observatory of Belgium
Ronny Blomme obtained his PhD in 1990 at the Vrije Universiteit Brussel. He is a staff member of the Royal Observatory of Belgium since 1989.
His main research interest is the stellar winds of massive stars. He observes these using both ground-based facilities (mainly radio telescopes) and space-borne ones. He studies how both small-scale and large-scale structure affect the stellar winds, and what happens when two of these winds collide in a binary system. He also uses hydrodynamics codes and develops radiative transfer codes to interpret the observed data. He is involved in the Gaia-ESO Survey, where he leads one of the working groups.
Ronny's Gaia involvement started in 2006. He develops one of the codes to determine the radial velocity from the RVS spectra and tests the scientific validity of such codes. He also works on the astrophysical parameter determination of hot stars.
