TESS Reveals HD 118203 b to be a Transiting Planet
Joshua Pepper, Stephen R. Kane, Joseph E. Rodriguez +30
The exoplanet HD 118203 b, orbiting a bright (V = 8.05) host star, was discovered using the radial velocity method by da Silva et al. (2006), but was not previously known to transi…
TOI-222: a single-transit TESS candidate revealed to be a 34-day eclipsing binary with CORALIE, EulerCam and NGTS
Monika Lendl, François Bouchy, Samuel Gill +58
We report the period, eccentricity, and mass determination for the TESS single-transit event candidate TOI-222, which displayed a single 3000 ppm transit in the TESS two-minute cad…
Three Red Suns in the Sky: A Transiting, Terrestrial Planet in a Triple M Dwarf System at 6.9 Parsecs
Jennifer G. Winters, Amber A. Medina, Jonathan M. Irwin +40
We present the discovery from TESS data of LTT 1445Ab. At a distance of 6.9 parsecs, it is the second nearest transiting exoplanet system found to date, and the closest one known f…
A super-Earth and sub-Neptune transiting the late-type M dwarf LP 791-18
Ian J. M. Crossfield, William Waalkes, Elisabeth R. Newton +57
Planets occur most frequently around cool dwarfs, but only a handful of specific examples are known to orbit the latest-type M stars. Using TESS photometry, we report the discovery…
Planetary system around the nearby M dwarf GJ 357 including a transiting, hot, Earth-sized planet optimal for atmospheric characterization
R. Luque, E. Pallé, D. Kossakowski +73
We report the detection of a transiting Earth-size planet around GJ 357, a nearby M2.5V star, using data from the Transiting Exoplanet Survey Satellite (TESS). GJ 357 b (TOI-562.01…
The L 98-59 System: Three Transiting, Terrestrial-Sized Planets Orbiting a Nearby M-dwarf
Veselin B. Kostov, Joshua E. Schlieder, Thomas Barclay +112
We report the Transiting Exoplanet Survey Satellite (TESS) discovery of three terrestrial-sized planets transiting L 98-59 (TOI-175, TIC 307210830) -- a bright M dwarf at a distanc…
HD 213885b: A transiting 1-day-period super-Earth with an Earth-like composition around a bright () star unveiled by TESS
Néstor Espinoza, Rafael Brahm, Thomas Henning +60
We report the discovery of the 1.008-day, ultra-short period (USP) super-Earth HD 213885b (TOI-141b) orbiting the bright () star HD 213885 (TOI-141, TIC 403224672), detected…
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…
Hot, rocky and warm, puffy super-Earths orbiting TOI-402 (HD 15337)
X. Dumusque, O. Turner, C. Dorn +30
TESS is revolutionising the search for planets orbiting bright and nearby stars. In sectors 3 and 4, TESS observed TOI-402 (TIC-120896927), a bright V=9.1 K1 dwarf also known as HD…
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…
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…
TESS delivers its first Earth-sized planet and a warm sub-Neptune
Diana Dragomir, Johanna Teske, Maximilian N. Gunther +48
The future of exoplanet science is bright, as TESS once again demonstrates with the discovery of its longest-period confirmed planet to date. We hereby present HD 21749b (TOI 186.0…
