Two young planetary systems around field stars with ages between 20-320 Myr from TESS

George Zhou, Samuel N. Quinn, Jonathan Irwin +46

Planets around young stars trace the early evolution of planetary systems. We report the discovery and validation of two planetary systems with ages $≲ 300$ Myr from observa…

The Magellan-TESS Survey I: Survey Description and Mid-Survey Results

Johanna Teske, Sharon Xuesong Wang, Angie Wolfgang +66

$K e pl er$ revealed that roughly one-third of Sun-like stars host planets orbiting within 100 days and between the size of Earth and Neptune. How do these planets form, what are they…

TOI-954 b and K2-329 b: Short-Period Saturn-Mass Planets that Test whether Irradiation Leads to Inflation

Lizhou Sha, Chelsea X. Huang, Avi Shporer +70

We report the discovery of two short-period Saturn-mass planets, one transiting the G subgiant TOI-954 (TIC 44792534, $V = 10.343$ , $T = 9.78$ ) observed in TESS sectors 4 and 5…

TOI-481 b & TOI-892 b: Two long period hot Jupiters from the Transiting Exoplanet Survey Satellite

Rafael Brahm, Louise D. Nielsen, Robert A. Wittenmyer +75

We present the discovery of two new 10-day period giant planets from the Transiting Exoplanet Survey Satellite ( $T E S S$ ) mission, whose masses were precisely determined using a wide…

A planetary system with two transiting mini-Neptunes near the radius valley transition around the bright M dwarf TOI-776

R. Luque, L. M. Serrano, K. Molaverdikhani +63

We report the discovery and characterization of two transiting planets around the bright M1 V star LP 961-53 (TOI-776, J = 8.5 mag, M = 0.54+-0.03 Msun) detected during Sector 10 o…

The TESS-Keck Survey II: An Ultra-Short Period Rocky Planet and its Siblings Transiting the Galactic Thick-Disk Star TOI-561

Lauren M. Weiss, Fei Dai, Daniel Huber +61

We report the discovery of TOI-561, a multi-planet system in the galactic thick disk that contains a rocky, ultra-short period planet (USP). This bright ( $V = 10.2$ ) star hosts three…

HATS-37Ab and HATS-38b: Two Transiting Hot Neptunes in the Desert

A. Jordán, G. Á. Bakos, D. Bayliss +24

We report the discovery of two transiting Neptunes by the HATSouth survey. The planet HATS-37Ab has a mass of 0.099 +- 0.042 M_J (31.5 +- 13.4 M_earth) and a radius of 0.606 +- 0.0…

The Compact Triply Eclipsing Triple Star TIC 209409435 Discovered with TESS

T. Borkovits, S. A. Rappaport, T. G. Tan +9

We report the discovery in $T E S S$ Sectors 3 and 4 of a compact triply eclipsing triple star system. TIC 209409435 is a previously unknown eclipsing binary with a period of 5.717 da…

OGLE-2017-BLG-0406: $Spitzer$ Microlens Parallax Reveals Saturn-mass Planet orbiting M-dwarf Host in the Inner Galactic Disk

Yuki Hirao, David P. Bennett, Yoon-Hyun Ryu +93

We report the discovery and analysis of the planetary microlensing event OGLE-2017-BLG-0406, which was observed both from the ground and by the $Spitzer$ satellite in a solar…

TESS spots a hot Jupiter with an inner transiting Neptune

Chelsea X. Huang, Samuel N. Quinn, Andrew Vanderburg +48

Hot Jupiters are rarely accompanied by other planets within a factor of a few in orbital distance. Previously, only two such systems have been found. Here, we report the discovery…

A remnant planetary core in the hot-Neptune desert

David J. Armstrong, Théo A. Lopez, Vardan Adibekyan +91

The interiors of giant planets remain poorly understood. Even for the planets in the Solar System, difficulties in observation lead to large uncertainties in the properties of plan…

Three Short Period Jupiters from TESS

L. D. Nielsen, R. Brahm, F. Bouchy +74

We report the confirmation and mass determination of three hot Jupiters discovered by the Transiting Exoplanet Survey Satellite (TESS) mission: HIP 65Ab (TOI-129, TIC-201248411) is…

Vetting of 384 TESS Objects of Interest with TRICERATOPS and Statistical Validation of 12 Planet Candidates

Steven Giacalone, Courtney D. Dressing, Eric L. N. Jensen +34

We present TRICERATOPS, a new Bayesian tool that can be used to vet and validate TESS Objects of Interest (TOIs). We test the tool on 68 TOIs that have been previously confirmed as…

GJ 1252 b: A 1.2 $R_{\oplus}$ planet transiting an M3-dwarf at 20.4 pc

Avi Shporer, Karen A. Collins, Nicola Astudillo-Defru +35

We report the discovery of GJ 1252 b, a planet with a radius of 1.193 $\pm$ 0.074 $R_{\oplus}$ and an orbital period of 0.52 days around an M3-type star (0.381 $\pm$ 0.019 $M_{\odo…
