A Second Planet Transiting LTT 1445A and a Determination of the Masses of Both Worlds Open
LTT 1445 is a hierarchical triple M-dwarf star system located at a distance of 6.86 pc. The primary star LTT 1445A (0.257 M ⊙ ) is known to host the transiting planet LTT 1445Ab with an orbital period of 5.36 days, making it the second-clo…

TOI-1431b/MASCARA-5b: A Highly Irradiated Ultrahot Jupiter Orbiting One of the Hottest and Brightest Known Exoplanet Host Stars Open
We present the discovery of a highly irradiated and moderately inflated ultrahot Jupiter, TOI-1431b/MASCARA-5 b (HD 201033b), first detected by NASA’s Transiting Exoplanet Survey Satellite mission (TESS) and the Multi-site All-Sky Camera (…

TOI-1431b/MASCARA-5b: An Ultra-hot Jupiter Orbiting One of the Hottest & Brightest Known Exoplanet Host Stars Open
Here I present the discovery of an ultra-hot Jupiter, TOI-1431b/MASCARA-5b, detected by TESS and MASCARA. Radial velocity measurements with SONG, SOPHIE, FIES, NRES, and EXPRES confirms the planet candidate with a reflex motion of K=294.1±…

Three Red Suns in the Sky: A Transiting, Terrestrial Planet in a Triple M-dwarf System at 6.9 pc Open
We present the discovery from Transiting Exoplanet Survey Satellite (TESS) data of LTT 1445Ab. At a distance of 6.9 pc, it is the second nearest transiting exoplanet system found to date, and the closest one known for which the primary is …

A second terrestrial planet orbiting the nearby M dwarf LHS 1140 Open
LHS 1140 is a nearby mid-M dwarf known to host a temperate rocky super-Earth (LHS 1140 b) on a 24.737-day orbit. Based on photometric observations by MEarth and Spitzer as well as Doppler spectroscopy from HARPS, we report the discovery of…
