Orbits and Masses for 156 Companions from Combined Astrometry and Radial Velocities, and A Validation of Gaia Non-Single Star Solutions

Qier An, Timothy D. Brandt, G. Mirek Brandt +1

We combine absolute astrometry from Hipparcos and Gaia with archival radial velocities from the Keck/HIRES and ESO/HARPS spectrographs, as well as relative astrometry (when availab…

A high mutual inclination system around KOI-134 revealed by transit timing variations

Emma Nabbie, Chelsea X. Huang, Judith Korth +9

Few planetary systems have measured mutual inclinations, and even less are found to be non-coplanar. Observing the gravitational interactions between exoplanets is an effective too…

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…

The mass of the exo-Venus Gliese 12 b, as revealed by HARPS-N, ESPRESSO, and CARMENES

Daisy A. Turner, Yoshi Nike Emilia Eschen, Felipe Murgas +60

Small temperate planets are prime targets for exoplanet studies due to their possible similarities with the rocky planets in the Solar System. M dwarfs are promising hosts since th…

Thermal Emission and Confirmation of the Frigid White Dwarf Exoplanet WD 1856+534b

Mary Anne Limbach, Andrew Vanderburg, Ryan J. MacDonald +12

We report the detection of thermal emission from and confirm the planetary nature of WD 1856+534b, the first transiting planet known to orbit a white dwarf star. Observations with…
