Description
The ERC «ASSESS» project aims to determine whether episodic mass loss is a dominant process in the evolution of the most massive stars by conducting the first extensive, multi-wavelength survey of evolved massive stars in the nearby Universe. The project hinges on the fact that mass-losing stars form dust and are bright in the mid-infrared. We investigate the properties of evolved targets, selected by mid-infrared archival photometry from Spitzer, in ~25 nearby galaxies and estimate the amount of ejected mass, which will constrain evolutionary models. In this work we present our first results from the northern hemisphere survey, which includes the galaxies NGC 6822 and IC 10.
