Giant Planets and Eccentric Orbits Are Common Around Galactic Thick Disc Stars

Thiago Ferreira, Jhon Yana Galarza, Henrique Reggiani +15

Planet formation in the Galactic thick disc is expected to be inefficient---low solid reservoirs, short disc lifetimes, and harsh irradiation environments should conspire to inhibi…

MANGOS II: Five new giant planets orbiting low-mass stars

G. Dransfield, M. Timmermans, D. Sebastian +47

Giant planets orbiting low-mass stars on short orbits present a conundrum, as in the most extreme cases their existence cannot be reconciled with current models of core accretion.…

The OATMEAL Survey. III. An Aligned Transiting Warm Brown Dwarf and Evidence for Quiescent Brown Dwarf Migration

Noah Vowell, Jiayin Dong, Joseph E. Rodriguez +7

We present the first measurement of the sky-projected orbital obliquity of a benchmark transiting brown dwarf host, HIP 33609, as a part of the Orbital Architectures of Transiting…

The TESS Grand Unified Hot Jupiter Survey. III. Thirty More Giant Planets

Samuel W. Yee, Joshua N. Winn, Joel D. Hartman +123

We present the discovery of 30 transiting giant planets that were initially detected using data from NASA's Transiting Exoplanet Survey Satellite (TESS) mission. These new planets…

An Eccentric Sub-Neptune Moving Into the Evaporation Desert

Sydney Jenkins, Andrew Vanderburg, Ritika Sethi +31

Though missions such as Kepler, K2, and TESS have discovered 2,000 sub-Neptune and Neptunian planets, there is a dearth of such planets at close-in (P3 days) orbits. T…

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…

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.…
