sYSOm generates emission maps of young stellar objects (YSOs) based on a model composed of a central star, modeled as a blackbody, and a dusty circumstellar disk. The disk is assumed to be geometrically flat with radial-dependent temperature and surface density prescribed by power laws.
The local intensity of the disk, seen at a given inclination, is then given by a blackbody emission at the local temperature weighted by an factor that depends on the local surface density and a chosen (…)

At the last SPIE meeting during the conference "Optical and Infrared Interferometry and Imaging VIII" prizes have been awarded to people deeply and succesfully involved on the development and the exploitation of interferometric instruments. Because the conference was held online two years ago during the pandemic, the ceremony included the 2020 awards.
The recipients were:
Guy Perrin, Fizeau Prize 2020 and Frank Eisenhauer, Michelson Investigator Prize 2020, both for, among other things, (…)
