Title: Uniformly Refining The Radii Of Earth-Sized Planets

PI: Lee, Rena - University Of Hawaii (Manoa)

Type: SMALL

Summary: Hundreds of transiting Earth-sized (<1.8 R_E) planets have been discovered in recent decades. Efforts to measure their masses (and compositions) are well underway thanks to the rise of extreme-precision radial velocity instruments and techniques. However, due to measurement uncertainties, the compositional diversity of the smallest (<1.2 R_E) planets remains elusive. The compositions Earth-sized planets are key to understanding terrestrial planet formation, evolution, and habitability. We propose to obtain 20-s cadence observations of 84 Earth-sized (<1.4 R_E) planets and planet candidates in TESS Cycle 8 to precisely measure or update their radii. This will prepare a large sample of Earths for detailed composition studies and atmospheric characterization with JWST.
