Astrobiology is the science that seeks to understand the story of life in our universe.
Astrobiology includes investigation of the conditions that are necessary for life to emerge …

Detailed characterization of an extrasolar planet's atmosphere provides the best hope for
distinguishing the makeup of its outer layers, and the only hope for understanding the …

Mass and radius are two of the most fundamental properties of an astronomical object.
Increasingly, new planet discoveries are being announced with a measurement of one of …

Abstract The Transiting Exoplanet Survey Satellite (TESS) has a goal of detecting small
planets orbiting stars bright enough for mass determination via ground-based radial velocity …

Several small dense exoplanets are now known, inviting comparisons to Earth and Venus.
Such comparisons require translating their masses and sizes to composition models of …

Variability in the light curves of spotted, rotating stars is often non-sinusoidal and quasi-
periodic–spots move on the stellar surface and have finite lifetimes, causing stellar flux …

The exoplanet population characterized by relatively short orbital periods (P< 100 d) around
solar-type stars is dominated by super-Earths and sub-Neptunes. However, these planets …

We report the discovery and characterization of a pair of sub-Neptunes transiting the bright K-
dwarf TOI-1064 (TIC 79748331), initially detected in the Transiting Exoplanet Survey …

ABSTRACT The Kepler Mission has discovered thousands of planets with radii< 4${R} _
{\oplus} $, paving the way for the first statistical studies of the dynamics, formation, and …

Abstract Since 2014, NASA's K2 mission has observed large portions of the ecliptic plane in
search of transiting planets and has detected hundreds of planet candidates. With …
