Assessing Planetary Stability and Long-Term Habitability in Nearby Stellar Binaries: 70 Oph, 36 Oph, $γ$ Leo

Alyssa R. Jankowski, Juliette Becker, Catherine A. Clark, Eric E. Mamajek et autres

Binary stars are common and have the potential to host habitable planets, which may reside in more complex habitable zones as compared to planets orbiting single stars. In this work, we use numerical simulations to assess the possibility that bright, nearby stellar …

The Ambiguous Age and Tidal History for the Ultra-Hot Jupiter TOI-1937Ab

Alyssa R. Jankowski, Juliette Becker, Melinda Soares-Furtado, Andrew M. Vanderburg et autres

Ultra-short-period (USP) planets are a rare but dynamically significant subset of the exoplanet sample, and understanding their dynamical histories and migration processes is necessary to build a complete picture of the outcomes of planet formation. In this work, we present an analysis …

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

Benjamin K. Capistrant, Melinda Soares-Furtado, Andrew M. Vanderburg, Alyssa R. Jankowski et autres

Abstract Young terrestrial worlds are critical test beds to constrain prevailing theories of planetary formation and evolution. We present the discovery of HD 63433 d—a nearby (22 pc), Earth-sized planet transiting a young Sun-like star (TOI-1726, HD 63433). HD 63433 d is …
