Stellar Winds in Time

Abstract

Exposure to stellar winds can have significant long term consequences for planetary atmospheres. Estimating the effects of these winds requires knowledge of how they evolve with time. Determining this empirically requires the ability to study the winds of stars of various ages and activity levels, but this is not easy to do as the coronal winds of solar-like stars are very hard to detect. Relevant observations are here reviewed, as well as more theoretical methods of addressing the problem.
