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 Myr from observa…
TOI 540 b: A Planet Smaller than Earth Orbiting a Nearby Rapidly Rotating Low-mass Star
Kristo Ment, Jonathan Irwin, David Charbonneau +20
We present the discovery of TOI 540 b, a hot planet slightly smaller than Earth orbiting the low-mass star 2MASS J05051443-4756154. The planet has an orbital period of $P = 1.23914…
TIC 278956474: Two close binaries in one young quadruple system, identified by \textit{TESS}
Pamela Rowden, Tamás Borkovits, Jon M. Jenkins +25
We have identified a quadruple system with two close eclipsing binaries in TESS data. The object is unresolved in Gaia and appears as a single source at parallax 1.08~0.01 mas…
The TESS-Keck Survey I: A Warm Sub-Saturn-mass Planet and a Caution about Stray Light in TESS Cameras
Paul A. Dalba, Arvind F. Gupta, Joseph E. Rodriguez +63
We report the detection of a Saturn-size exoplanet orbiting HD 332231 (TOI 1456) in light curves from the Transiting Exoplanet Survey Satellite (TESS). HD 332231, an F8 dwarf star…
KELT-9 b's Asymmetric TESS Transit Caused by Rapid Stellar Rotation and Spin-Orbit Misalignment
John P. Ahlers, Marshall C. Johnson, Keivan G Stassun +19
KELT-9 b is an ultra hot Jupiter transiting a rapidly rotating, oblate early-A-type star in a polar orbit. We model the effect of rapid stellar rotation on KELT-9 b's transit light…
A Habitable-Zone Earth-Sized Planet Rescued from False Positive Status
Andrew Vanderburg, Pamela Rowden, Steve Bryson +9
We report the discovery of an Earth-sized planet in the habitable zone of a low-mass star called Kepler-1649. The planet, Kepler-1649 c, is 1.06 times the size of…
LHS 1815b: The First Thick-Disk Planet Detected By TESS
Tianjun Gan, Avi Shporer, John H. Livingston +35
We report the first discovery of a thick-disk planet, LHS 1815b (TOI-704b, TIC 260004324), detected in the TESS survey. LHS 1815b transits a bright (V = 12.19 mag, K = 7.99 mag) an…
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…
TOI-257b (HD 19916b): A Warm sub-Saturn Orbiting an Evolved F-type Star
Brett C. Addison, Duncan J. Wright, Belinda A. Nicholson +91
We report the discovery of a warm sub-Saturn, TOI-257b (HD 19916b), based on data from NASA's Transiting Exoplanet Survey Satellite (TESS). The transit signal was detected by TESS…
