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-677 b: A Warm Jupiter (P=11.2d) on an eccentric orbit transiting a late F-type star
Andrés Jordán, Rafael Brahm, Néstor Espinoza +46
We report the discovery of TOI-677 b, first identified as a candidate in light curves obtained within Sectors 9 and 10 of the Transiting Exoplanet Survey Satellite (TESS) mission a…
A Catalog of Periodic Variables in Open Clusters M35 and NGC 2158
M. Soares-Furtado, J. D. Hartman, W. Bhatti +3
We present a catalog of 1,143 periodic variables, compiled from our image-subtracted photometric analysis of the K2 Campaign-0 super stamp. This super stamp is centered on the open…
Cluster Difference Imaging Photometric Survey. I. Light Curves of Stars in Open Clusters from TESS Sectors 6 & 7
L. G. Bouma, J. D. Hartman, W. Bhatti +2
The Transiting Exoplanet Survey Satellite (TESS) is providing precise time-series photometry for most star clusters in the solar neighborhood. Using the TESS images, we have begun…
TESS Hunt for Young and Maturing Exoplanets (THYME): A planet in the 45 Myr Tucana-Horologium association
Elisabeth R. Newton, Andrew W. Mann, Benjamin M. Tofflemire +49
Young exoplanets are snapshots of the planetary evolution process. Planets that orbit stars in young associations are particularly important because the age of the planetary system…
TOI-216b and TOI-216c: Two warm, large exoplanets in or slightly wide of the 2:1 orbital resonance
Rebekah I. Dawson, Chelsea X. Huang, Jack J. Lissauer +32
Warm, large exoplanets with 10-100 day orbital periods pose a major challenge to our understanding of how planetary systems form and evolve. Although high eccentricity tidal migrat…
Complex Rotational Modulation of Rapidly Rotating M-Stars Observed with TESS
Z. Zhan, M. N. Günther, S. Rappaport +23
We have searched for short periodicities in the light curves of stars with cooler than 4000 K made from 2-minute cadence data obtained in TESS sectors 1 and 2. Herein…
A super-Earth and two sub-Neptunes transiting the nearby and quiet M dwarf TOI-270
Maximilian N. Günther, Francisco J. Pozuelos, Jason A. Dittmann +57
We report the Transiting Exoplanet Survey Satellite discovery of three small planets transiting one of the nearest and brightest M dwarf hosts to date, TOI-270 (TIC 259377017; K-ma…
WASP-4b Arrived Early for the TESS Mission
L. G. Bouma, J. N. Winn, C. Baxter +21
The Transiting Exoplanet Survey Satellite (TESS) recently observed 18 transits of the hot Jupiter WASP-4b. The sequence of transits occurred 81.6 11.7 seconds earlier than ha…
Deep Long Asymmetric Occultation in EPIC 204376071
S. Rappaport, G. Zhou, A. Vanderburg +15
We have discovered a young M star of mass and radius , likely in the Upper Sco Association, that exhibits only a single deep occultation of 1-…
Near-resonance in a system of sub-Neptunes from TESS
Samuel N. Quinn, Juliette C. Becker, Joseph E. Rodriguez +78
We report the Transiting Exoplanet Survey Satellite () detection of a multi-planet system orbiting the K0 dwarf TOI 125. We find evidence for up to five planets, wit…
An Eccentric Massive Jupiter Orbiting a Sub-Giant on a 9.5 Day Period Discovered in the Transiting Exoplanet Survey Satellite Full Frame Images
Joseph E. Rodriguez, Samuel N. Quinn, Chelsea X. Huang +71
We report the discovery of TOI-172 b from the Transiting Exoplanet Survey Satellite (TESS) mission, a massive hot Jupiter transiting a slightly evolved G-star with a 9.48-day orbit…
