KELT-25b and KELT-26b: A Hot Jupiter and a Substellar Companion Transiting Young A-stars Observed by TESS

Romy Rodríguez Martínez, B. Scott Gaudi, Joseph E. Rodriguez +89

We present the discoveries of KELT-25b (TIC 65412605, TOI-626.01) and KELT-26b (TIC 160708862, TOI-1337.01), two transiting companions orbiting relatively bright, early A-stars. Th…

TOI-132 b: A short-period planet in the Neptune desert transiting a G-type star

Matías R. Díaz, James S. Jenkins, Davide Gandolfi +45

The Neptune desert is a feature seen in the radius-mass-period plane, whereby a notable dearth of short period, Neptune-like planets is found. Here we report the {\it TESS} discove…

Zodiacal Exoplanets in Time (ZEIT) IX: a flat transmission spectrum and a highly eccentric orbit for the young Neptune K2-25b as revealed by Spitzer

Pa Chia Thao, Andrew W. Mann, Marshall C. Johnson +9

Transiting planets in nearby young clusters offer the opportunity to study the atmospheres and dynamics of planets during their formative years. To this end, we focused on K2-25b -…

Radial Velocity Discovery of an Eccentric Jovian World Orbiting at 18 au

Sarah Blunt, Michael Endl, Lauren M. Weiss +25

Based on two decades of radial velocity (RV) observations using Keck/HIRES and McDonald/Tull, and more recent observations using the Automated Planet Finder, we found that the near…

TOI-503: The first known brown dwarf-Am star binary from the TESS mission

Ján Šubjak, Rishikesh Sharma, Theron W. Carmichael +76

We report the discovery of an intermediate-mass transiting brown dwarf, TOI-503b, from the TESS mission. TOI-503b is the first brown dwarf discovered by TESS and orbits a metallic-…
