K2-280b -- a low density warm sub-Saturn around a mildly evolved star
Grzegorz Nowak, Enric Palle, Davide Gandolfi +57
We present an independent discovery and detailed characterisation of K2-280b, a transiting low density warm sub-Saturn in a 19.9-day moderately eccentric orbit (e = 0.35_{-0.04}^{+…
TESS Hunt for Young and Maturing Exoplanets (THYME) III: a two-planet system in the 400 Myr Ursa Major Group
Andrew W. Mann, Marshall C. Johnson, Andrew Vanderburg +51
Exoplanets can evolve significantly between birth and maturity, as their atmospheres, orbits, and structures are shaped by their environment. Young planets (1 Gyr) offer an oppo…
KELT-9 b's Asymmetric TESS Transit Caused by Rapid Stellar Rotation and Spin-Orbit Misalignment
John P. Ahlers, Marshall C. Johnson, Keivan G Stassun +19
KELT-9 b is an ultra hot Jupiter transiting a rapidly rotating, oblate early-A-type star in a polar orbit. We model the effect of rapid stellar rotation on KELT-9 b's transit light…
Doppler Tomographic Measurement of the Nodal Precession of WASP-33b
Noriharu Watanabe, Norio Narita, Marshall C. Johnson
WASP-33b is a retrograde hot Jupiter with a period of 1.2 days orbiting around a rapidly rotating and pulsating A-type star. A previous study found that the transit chord of WASP-3…
