About the NASA Postdoctoral Program
The NASA Postdoctoral Program (NPP) offers unique research opportunities to highly-talented scientists to engage in ongoing NASA research projects at a NASA Center, NASA Headquarters, or at a NASA-affiliated research institute. These one- to three-year fellowships are competitive and are designed to advance NASA’s missions in space science, Earth science, aeronautics, space operations, exploration systems, and astrobiology.
Description:
How do the properties of a planet and its host star influence its ability to retain an atmosphere? The Retention of Habitable Atmospheres in Planetary Systems (RHAPS) team is working to address this question by bringing together modelers and observers who study Earth, solar system planets, and exoplanets to model atmospheric escape via all known escape processes for a variety of star-planet scenarios. Our effort consists of four tasks: (1) Compute the stellar inputs for planetary escape for exoplanet hosting stars; (2) Improve and link models for atmospheric escape from any planet; (3) Construct a multi-dimensional model library for atmospheric escape; and (4) Apply the model library to understand the connection between atmospheric escape, habitability, and observations. Major results from the effort will include 150-200 complete sets of input conditions, a web interface to all model results, escape rates from competing models in many instances, estimates of ‘atmospheric lifetimes’ for each scenario, and predictions for exoplanet transit observations. Our research complements the goals of the NExSS RCN, where stellar radiation, climate, and magnetic fields are all mentioned as topics of interest.
