Non-thermal emission from early-type stars
Abstract
Description
Massive, early-type stars deposit energy and momentum in the interstellar medium through dense, supersonic winds. These objects are one of the most important sources of ionising radiation and chemical enrichment in the Galaxy. The physical conditions in the winds give rise to thermal and non-thermal emission, detectable from radio to gamma rays. In this report the relevant radiation processes will be described and studies on particular systems will be presented, discussing the information provided by multifrequency observations. Future steps aiming at understanding the stellar wind phenomenon as a whole will be outlined.
