Atmospheric Escape and Replenishment in Planetary Systems Workshop
About Event
Location
Space Telescope Science Institute (STScI)
3700 San Martin Drive
Baltimore, MD 21218
Description
The competition between atmospheric mass-loss through escape versus replenishment by outgassing determines the formation, evolution, and ultimate fate of planetary atmospheres inside and outside the Solar System. New discoveries have been possible through space-based spectroscopy from HST and JWST, high-resolution ground-based spectroscopy in the optical and near-infrared, and in situ Solar System exploration. The future is promising with the public data coming out of STScI’s Rocky Worlds DDT program and the development of the Habitable Worlds Observatory. In this workshop, we will discuss the theoretical aspects involved in atmospheric escape and replenishment through outgassing, as well as study the best strategies to observe them. We selected key outstanding questions related to this topic and invite the community of planetary and exoplanetary scientists to work together in exploring answers.
Main Science Questions
- What observational strategies maximize information content about the physics of atmospheric escape?
- What observational strategies maximize information content about the presence and/or properties of secondary atmospheres?
- What are the conditions necessary for outgassing a secondary atmosphere?
- Can rocky planets around M dwarfs retain detectable secondary atmospheres?
- What is the role of atmospheric chemical makeup in regulating hydrodynamic escape?
- How can we accurately describe the physics that shape exospheres?
