Betelgeuse Workshop 2012

November 26-29, 2012

Venue: Paris Observatory, France

Mass loss from evolved massive stars is a major contributor to the chemical enrichment of the interstellar medium, the Galaxy, and ultimately the Universe. To have a clear view of their cosmic impact, it is essential to understand their physics, from the photosphere to the interstellar medium (ISM). Thanks to its proximity and brightness, Betelgeuse is a particularly important fiducial object to study in details the physical phenomena at play in red supergiants (RSGs).
The goal of the workshop is to assemble a comprehensive description of the different regions constitutive of Betelgeuse, to understand how they interact with each other, and eventually how red supergiants are functioning.
We aim at a genuine workshop format with many opportunities for exchanges among 50 participants who actively carry out research on Betelgeuse and similar objects. Each session will start with an invited overview talk and will be closed by a discussion.
