Destruction of "Peas in a Pod?" A Candidate Multi-planet System Around the Nearby, Bright Star, HD208487

Rafael I. Rubenstein, James S. Jenkins, Pablo A. Peña R. +15

We re-investigate the HD208487 system to test the reality of the proposed HD208487c world. We also search for additional companions using applied Bayesian statistics and 15+ years…

HD 35843: A Sun-like star hosting a long period sub-Neptune and inner super-Earth

Katharine Hesse, Ismael Mireles, François Bouchy +52

We report the discovery and confirmation of two planets orbiting the metal-poor Sun-like star, HD 35843 (TOI 4189). HD 35843 c is a temperate sub-Neptune transiting planet with an…

TOI-2005b: An Eccentric Warm Jupiter in Spin-Orbit Alignment

Allyson Bieryla, Jiayin Dong, George Zhou +36

We report the discovery and characterization of TOI-2005b, a warm Jupiter on an eccentric (e~0.59), 17.3-day orbit around a V_mag = 9.867 rapidly rotating F-star. The object was de…

The Super-Puff WASP-193b is On A Well-Aligned Orbit

Samuel W. Yee, Gudmundur Stefansson, Daniel Thorngren +8

The "super-puffs" are a population of planets that have masses comparable to that of Neptune but radii similar to Jupiter, leading to extremely low bulk densities ($ρ_p \lesssim 0.…
