Two Warm Super-Earths Transiting the Nearby M Dwarf TOI-2095

Elisa V. Quintana, Emily A. Gilbert, Thomas Barclay +55

We report the detection and validation of two planets orbiting TOI-2095 (TIC 235678745). The host star is a 3700K M1V dwarf with a high proper motion. The star lies at a distance o…

Absence of extended atmospheres in low-mass star radius-gap planets GJ 9827 b, GJ 9827 d and TOI-1235 b

Vigneshwaran Krishnamurthy, Teruyuki Hirano, Eric Gaidos +20

\textit{Kepler} showed a paucity of planets with radii of 1.5 - 2 around solar mass stars but this radius-gap has not been well studied for low-mass star plane…

The transmission spectrum of the potentially rocky planet L 98-59 c

Thomas Barclay, Kyle B. Sheppard, Natasha Latouf +32

We present observations of the 1.35+/-0.07 Earth-radius planet L 98-59 c, collected using Wide Field Camera 3 on the Hubble Space Telescope. L 98-59 is a nearby (10.6 pc), bright (…

Removal of Hot Saturns in Mass-Radius Plane by Runaway Mass Loss

Daniel P. Thorngren, Eve J. Lee, Eric D. Lopez

The hot Saturn population exhibits a boundary in mass-radius space, such that no planets are observed at a density less than 0.1 g cm. Yet, planet interior structure m…

The sub-Neptune desert and its dependence on stellar type: Controlled by lifetime X-ray irradiation

George D. McDonald, Laura Kreidberg, Eric Lopez

Short-period sub-Neptunes with substantial volatile envelopes are among the most common type of known exoplanets. However, recent studies of the Kepler population have suggested a…
