SUMMARY:Retention of Habitable Atmospheres in Planetary System
LOCATION:Young Hall 4222
DESCRIPTION:Presented by: Prof. David Brain

Affiliation: University of Colorado Boulder

Location: 3853 Slichter Hall

 Abstract:Planetary atmospheres are not static in time\, and the many changes they experience can contribute to making a planet’s surface a more (or less) hospitable place. Interactions between a planet and its host star are especially important. They not only control the temperature of an atmosphere but can also drive atmospheric escape and atmospheric chemistry. In this presentation I describe ongoing efforts to understand what characteristics of a planet and its star\, when combined together\, allow the planet to retain an atmosphere that might be habitable at the planet’s surface. I’ll describe observations from planets in our solar system that inform this work\, relevant modeling and observational efforts\, and a team science effort dedicated to answering this guiding question.
