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
11:00 A.M. in 169-336

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.
