2020 Sagan Exoplanet Summer Workshop

Extreme Precision Radial Velocity

July 20-24, 2020
Hosted by The NASA Exoplanet Science Institute
California Institute of Technology, Pasadena, CA




Join us in 2020 for the 20th Sagan Summer Workshop! This year we will focus on the technique of Extreme Precision Radial Velocity (EPRV) for finding and characterizing exoplanets. The recent National Academy of Sciences (NAS) Exoplanet Strategy Report highlighted EPRV as a critical technique for advancing the goal of finding and characterizing potentially habitable Earth analogs. With expected radial velocity signals that are an order of magnitude (or more) smaller than the currently best achieved results, EPRV observations are necessary to measure the masses and orbits of Earth analogs orbiting nearby stars. These nearby planetary systems are expected to be the targets for future planetary direct imaging programs with LUVOIR and HabEx in space, and the Extremely Large Telescopes on the ground. These observatories will also provide detailed spectra that require information on the planet masses in order to determine atmospheric content and the potential for habitability. This workshop will provide an introduction to the basics of the PRV technique, a summary of planet demographics from PRV surveys, and an evaluation of the importance of planet masses and orbits to imaging missions and of the challenges in advancing PRV precision by the factor of 10-30 needed to detect terrestrial analogs in orbit around nearby solar type stars.

Attendees will also participate in hands-on group projects and will have the opportunity to present their own work through short presentations (research POPs) and posters.

Registration and information on financial assistance to attend the workshop will be available in February 2020. Check back often as we add information to this site!

We ask all participants to follow this Code of Conduct.
