A long spin period for a sub-Neptune-mass exoplanet

Ellen M. Price, Juliette Becker, Zoë L. de Beurs +2

HIP 41378 f is a sub-Neptune exoplanet with an anomalously low density. Its long orbital period and deep transit make it an ideal candidate for detecting oblateness photometrically…

Detection of an Earth-sized exoplanet orbiting the nearby ultracool dwarf star SPECULOOS-3

Michaël Gillon, Peter P. Pedersen, Benjamin V. Rackham +81

Located at the bottom of the main sequence, ultracool dwarf stars are widespread in the solar neighbourhood. Nevertheless, their extremely low luminosity has left their planetary p…

The coevolution of migrating planets and their pulsating stars through episodic resonance locking

Jared Bryan, Julien de Wit, Meng Sun +2

Hot Jupiters are expected to form far from their host star and move toward close-in, circular orbits via a smooth, monotonic decay due to mild and constant tidal dissipation. Yet,…

Characterization of K2-167 b and CALM, a new stellar activity mitigation method

Zoë L. de Beurs, Andrew Vanderburg, Erica Thygesen +13

We report precise radial velocity (RV) observations of HD 212657 (= K2-167), a star shown by K2 to host a transiting sub-Neptune-sized planet in a 10 day orbit. Using Transiting Ex…

TESS Hunt for Young and Maturing Exoplanets (THYME) XI: An Earth-sized Planet Orbiting a Nearby, Solar-like Host in the 400Myr Ursa Major Moving Group

Benjamin K. Capistrant, Melinda Soares-Furtado, Andrew Vanderburg +32

Young terrestrial worlds are critical test beds to constrain prevailing theories of planetary formation and evolution. We present the discovery of HD 63433d - a nearby (22pc), Eart…
