TOI-2109b: An Ultrahot Gas Giant on a 16 hr Orbit
Ian Wong, Avi Shporer, George Zhou +56
We report the discovery of an ultrahot Jupiter with an extremely short orbital period of days (16 hr). The plane…
TOI-712: a system of adolescent mini-Neptunes extending to the habitable zone
Sydney Vach, Samuel N. Quinn, Andrew Vanderburg +40
As an all-sky survey, NASA's mission is able to detect the brightest and rarest types of transiting planetary systems, including young planets that enable study of the evolu…
TOI-2076 and TOI-1807: Two young, comoving planetary systems within 50 pc identified by TESS that are ideal candidates for further follow-up
Christina Hedges, Alex Hughes, Steven Giacalone +42
We report the discovery of two planetary systems around comoving stars; TOI-2076 (TIC 27491137) and TOI-1807 (TIC 180695581). TOI-2076 is a nearby (41.9 pc) multi-planetary system…
TIC 5724661: A Long-Period Binary with a Pulsating sdB Star and Scuti Variable
Rahul Jayaraman, Saul Rappaport, Lorne Nelson +8
Using TESS 20-sec cadence data, we have discovered an unusual combination of pulsating stars in what we infer to be a binary system. The binary consists of a standard Scuti sta…
The obliquity of HIP 67522 b: a 17 Myr old transiting hot Jupiter-sized planet
Alexis Heitzmann, George Zhou, Samuel N. Quinn +7
HIP 67522 b is a 17 Myr old, close-in ( d), Jupiter-sized () transiting planet orbiting a Sun like star in the Sco-Cen OB association. We presen…
An Aligned Orbit for the Young Planet V1298 Tau b
Marshall C. Johnson, Trevor J. David, Erik A. Petigura +22
The alignment of planetary orbits with respect to the stellar rotation preserves information on their dynamical histories. Measuring this angle for young planets help illuminate th…
TOI-3362b: A Proto-Hot Jupiter Undergoing High-Eccentricity Tidal Migration
Jiayin Dong, Chelsea X. Huang, George Zhou +39
High-eccentricity tidal migration is a possible way for giant planets to be emplaced in short-period orbits. If it commonly operates, one would expect to catch proto-Hot Jupiters o…
TOI-1518b: A Misaligned Ultra-hot Jupiter with Iron in its Atmosphere
Samuel H. C. Cabot, Aaron Bello-Arufe, João M. Mendonça +36
We present the discovery of TOI-1518b -- an ultra-hot Jupiter orbiting a bright star . The transiting planet is confirmed using high-resolution optical transmission spect…
Giants Transiting Giants I: A Non-inflated Hot Jupiter Orbiting a Massive Subgiant
Nicholas Saunders, Samuel K. Grunblatt, Daniel Huber +27
While the population of confirmed exoplanets continues to grow, the sample of confirmed transiting planets around evolved stars is still limited. We present the discovery and confi…
Populating the brown dwarf and stellar boundary: Five stars with transiting companions near the hydrogen-burning mass limit
Nolan Grieves, François Bouchy, Monika Lendl +52
We report the discovery of five transiting companions near the hydrogen-burning mass limit in close orbits around main sequence stars originally identified by the Transiting Exopla…
TOI-942b: A Prograde Neptune in a ~60 Myr old Multi-transiting System
Christopher P. Wirth, George Zhou, Samuel N. Quinn +8
Mapping the orbital obliquity distribution of young planets is one avenue towards understanding mechanisms that sculpt the architectures of planetary systems. TOI-942 is a young fi…
TESS Hunt for Young and Maturing Exoplanets (THYME) V: A Sub-Neptune Transiting a Young Star in a Newly Discovered 250 Myr Association
Benjamin M. Tofflemire, Aaron C. Rizzuto, Elisabeth R. Newton +27
The detection and characterization of young planetary systems offers a direct path to study the processes that shape planet evolution. We report on the discovery of a sub-Neptune-s…
TESS Hunt for Young and Maturing Exoplanets (THYME) IV: Three small planets orbiting a 120 Myr-old star in the Pisces--Eridanus stream
Elisabeth R. Newton, Andrew W. Mann, Adam L. Kraus +50
Young exoplanets can offer insight into the evolution of planetary atmospheres, compositions, and architectures. We present the discovery of the young planetary system TOI 451 (TIC…
TESS Delivers Five New Hot Giant Planets Orbiting Bright Stars from the Full Frame Images
