The Promise, Prospects, and Challenges of Precision Radial Velocity
Presented by Suvrath Mahadevan
Department of Astronomy and Astrophysics, Pennsylvania State University

Thursday, June 28, 2018

Abstract
The increasing precision of Doppler Radial Velocity, photometry and spectroscopy of exoplanet atmospheres has dramatically altered our understanding of exoplanets and planetary systems. I will discuss how current advances in instrumentation and techniques, coupled with large-scale surveys, is poised to push the boundaries of exoplanet discovery and characterization with Doppler RVs. Using the Habitable Zone Planet Finder (HPF) and NEID as examples, I shall highlight the observational, instrumental and astrophysical challenges in pushing to every higher differential velocity precision in the near infrared and the optical, where we stand as a field, and possible paths through the barrier posed by the intrinsic activity of the stars themselves.
