Description
Advancing Precision Spectroscopy and Detecting Earth Analogs
Extreme precision radial velocity (EPRV) measurements, capable of capturing signals with an amplitude of just 10-30 cm/s, are needed to needed to uncover low-mass planets and inform planet formation scenarios, calculate planetary interior composition, and constrain atmospheric models. This need has given rise to innovation in precision spectroscopy at all levels--from the instrumentation to the extraction software through to the astrophysics guiding the final derived RV measurements. I will give an overview of the recent advances across the EPRV community and how they shape the future of the field. Building on a baseline of 6+ years of EPRV-quality data, we can now explore information-complete algorithms to find Earths, optimize instrumentation, and image stellar surfaces.
