Two Earth-size Planets and an Earth-size Candidate Transiting the Nearby Star HD 101581

Michelle Kunimoto, Zifan Lin, Sarah Millholland +43

We report the validation of multiple planets transiting the nearby ( pc) K5V dwarf HD 101581 (GJ 435, TOI-6276, TIC 397362481). The system consists of at least two Earth-…

Serendipitous observation of a white dwarf companion to a JWST/MIRI coronagraphic calibrator

Alexander Venner, Mary Anne Limbach, Mathilde Mâlin +3

We present the unplanned detection of a white dwarf companion to the star HD 218261 in mid-infrared (10-16 m) observations with JWST/MIRI. This star was observed as a calibrator…

A catalog of binary stars from phase modulation in the first four years of TESS Mission photometry

Shishir Dholakia, Simon J. Murphy, Chelsea X. Huang +2

We present a catalog of binary companions to Scuti stars, detected through phase modulations of their pulsations in TESS data. Pulsation timing has provided orbits for hundreds…

HD 28185 Revisited: An Outer Planet, Instead of a Brown Dwarf, On a Saturn-like Orbit

Alexander Venner, Qier An, Chelsea X. Huang +3

As exoplanet surveys reach ever-higher sensitivities and durations, planets analogous to the solar system giant planets are increasingly within reach. HD 28185 is a Sun-like star k…

The K2 and TESS Synergy III: search and rescue of the lost ephemeris for K2's first planet

Erica Thygesen, Joseph E. Rodriguez, Zoë L. De Beurs +13

K2-2 b/HIP 116454 b, the first exoplanet discovery by K2 during its Two-Wheeled Concept Engineering Test, is a sub-Neptune (2.5 0.1 , 9.7 1.2 ) orbi…

The MIRI Exoplanets Orbiting White Dwarfs (MEOW) Survey: Mid-Infrared Excess Reveals a Giant Planet Candidate around a Nearby White Dwarf

Mary Anne Limbach, Andrew Vanderburg, Alexander Venner +17

The MIRI Exoplanets Orbiting White dwarfs (MEOW) Survey is a cycle 2 JWST program to search for exoplanets around dozens of nearby white dwarfs via infrared excess and direct imagi…

Gliese 12 b, A Temperate Earth-sized Planet at 12 Parsecs Discovered with TESS and CHEOPS

Shishir Dholakia, Larissa Palethorpe, Alexander Venner +33

We report on the discovery of Gliese 12 b, the nearest transiting temperate, Earth-sized planet found to date. Gliese 12 is a bright ( mag, mag) metal-poor M4V star…
