An Ultra-Hot Neptune in the Neptune desert
James S. Jenkins, MatÃas R. DÃaz, Nicolás T. Kurtovic +81
About one out of 200 Sun-like stars has a planet with an orbital period shorter than one day: an ultra-short-period planet (Sanchis-ojeda et al. 2014; Winn et al. 2018). All of the…
A pair of warm giant planets near the 2:1 mean motion resonance around the K-dwarf star TOI-2202
Trifon Trifonov, Rafael Brahm, Nestor Espinoza +37
TOI-2202 b is a transiting warm Jovian-mass planet with an orbital period of P=11.91 days identified from the Full Frame Images data of five different sectors of the TESS mission.…
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…
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 () mission, whose masses were precisely determined using a wide…
HD 1397b: a transiting warm giant planet orbiting a V = 7.8 mag sub-giant star discovered by TESS
Rafael Brahm, Néstor Espinoza, Andrés Jordán +11
We report the discovery of a transiting planet first identified as a candidate in Sector 1 of the Transiting Exoplanet Survey Satellite (TESS), and then confirmed with precision ra…
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, , ) observed in TESS sectors 4 and 5…
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…
Precise transit and radial-velocity characterization of a resonant pair: a warm Jupiter TOI-216c and eccentric warm Neptune TOI-216b
Rebekah I. Dawson, Chelsea X. Huang, Rafael Brahm +53
TOI-216 hosts a pair of warm, large exoplanets discovered by the TESS Mission. These planets were found to be in or near the 2:1 resonance, and both of them exhibit transit timing…
Three long period transiting giant planets from TESS
Rafael Brahm, Solène Ulmer-Moll, Melissa J. Hobson +52
We report the discovery and orbital characterization of three new transiting warm giant planets. These systems were initially identified as presenting single transit events in the…
