Recent astronomical observations obtained with the Kepler and TESS missions and their related ground-based follow-ups revealed an abundance of exoplanets with a size intermediate b…
K2-79b and K2-222b: Mass measurements of two small exoplanets with periods beyond 10 days that overlap with periodic magnetic activity signals
Chantanelle Nava, Mercedes López-Morales, Annelies Mortier +28
We present mass and radius measurements of K2-79b and K2-222b, two transiting exoplanets orbiting active G-type stars. Their respective 10.99d and 15.39d orbital periods fall near…
Confirmation of WASP-107b's extended Helium atmosphere with Keck II/NIRSPEC
James Kirk, Munazza K. Alam, Mercedes Lopez-Morales +1
We present the detection of helium in the extended atmosphere of the sub-Saturn WASP-107b using high resolution () near-infrared spectra from Keck II/NIRSPEC. We f…
An ultra-short period rocky super-Earth orbiting the G2-star HD 80653
G. Frustagli, E. Poretti, T. Milbourne +26
Ultra-short period (USP) planets are a class of exoplanets with periods shorter than one day. The origin of this sub-population of planets is still unclear, with different formatio…
Homogeneous Analysis of Hot Earths: Masses, Sizes, and Compositions
Fei Dai, Kento Masuda, Joshua N. Winn +1
Terrestrial planets have been found orbiting Sun-like stars with extremely short periods --- some as short as 4 hours. These "ultra-short-period planets" or "hot Earths" are so str…
An 11 Earth-Mass, Long-Period Sub-Neptune Orbiting a Sun-like Star
Andrew W. Mayo, Vinesh M. Rajpaul, Lars A. Buchhave +27
Although several thousands of exoplanets have now been detected and characterized, observational biases have led to a paucity of long-period, low-mass exoplanets with measured mass…
