TOI 560 : Two Transiting Planets Orbiting a K Dwarf Validated with iSHELL, PFS and HIRES RVs
Mohammed El Mufti, Peter P. Plavchan, Howard Isaacson +92
We validate the presence of a two-planet system orbiting the 0.15--1.4 Gyr K4 dwarf TOI 560 (HD 73583). The system consists of an inner moderately eccentric transiting mini-Neptune…
HD207897 b: A dense sub-Neptune transiting a nearby and bright K-type star
N. Heidari, I. Boisse, J. Orell-Mique +90
We present the discovery and characterization of a transiting sub-Neptune orbiting with a 16.20 day period around a nearby (28 pc) and bright(V=8.37) K0V star HD207897 (TOI-1611).…
The TESS-Keck Survey. VI. Two Eccentric sub-Neptunes Orbiting HIP-97166
Mason G. MacDougall, Erik A. Petigura, Isabel Angelo +45
We report the discovery of HIP-97166b (TOI-1255b), a transiting sub-Neptune on a 10.3-day orbit around a K0 dwarf 68 pc from Earth. This planet was identified in a systematic searc…
Another super-dense sub-Neptune in K2-182 b and refined mass measurements for K2-199 b and c
Joseph M. Akana Murphy, Molly R. Kosiarek, Natalie M. Batalha +10
We combine multiple campaigns of K2 photometry with precision radial velocity measurements from Keck-HIRES to measure the masses of three sub-Neptune-size planets. We confirm the p…
TKS V. Twin sub-Neptunes Transiting the Nearby G Star HD 63935
Nicholas Scarsdale, Joseph M. Akana Murphy, Natalie M. Batalha +56
We present the discovery of two nearly identically-sized sub-Neptune transiting planets orbiting HD 63935, a bright ( mag), sun-like () star at 49 pc. TESS id…
TOI-431/HIP 26013: a super-Earth and a sub-Neptune transiting a bright, early K dwarf, with a third RV planet
Ares Osborn, David J. Armstrong, Bryson Cale +125
We present the bright (V), multi-planet system TOI-431, characterised with photometry and radial velocities. We estimate the stellar rotation period to be $30.5 \pm…
TESS-Keck Survey IX: Masses of Three Sub-Neptunes Orbiting HD 191939 and the Discovery of a Warm Jovian Plus a Distant Sub-Stellar Companion
Jack Lubin, Judah Van Zandt, Rae Holcomb +32
Exoplanet systems with multiple transiting planets are natural laboratories for testing planetary astrophysics. One such system is HD 191939 (TOI-1339), a bright (V=9) and Sun-like…
The TESS-Keck Survey: Science Goals and Target Selection
Ashley Chontos, Joseph M. Akana Murphy, Mason G. MacDougall +28
Space-based transit missions such as Kepler and TESS have demonstrated that planets are ubiquitous. However, the success of these missions heavily depends on ground-based radial ve…
TKS X: Confirmation of TOI-1444b and a Comparative Analysis of the Ultra-short-period Planets with Hot Neptunes
Fei Dai, Andrew W. Howard, Natalie M. Batalha +48
We report the discovery of TOI-1444b, a 1.4- super-Earth on a 0.47-day orbit around a Sun-like star discovered by {\it TESS}. Precise radial velocities from Keck/HIRES co…
The TESS Objects of Interest Catalog from the TESS Prime Mission
Natalia M. Guerrero, S. Seager, Chelsea X. Huang +102
We present 2,241 exoplanet candidates identified with data from the Transiting Exoplanet Survey Satellite (TESS) during its two-year prime mission. We list these candidates in the…
The TESS-Keck Survey IV: A Retrograde, Polar Orbit for the Ultra-Low-Density, Hot Super-Neptune WASP-107b
Ryan A. Rubenzahl, Fei Dai, Andrew W. Howard +21
We measured the Rossiter-McLaughlin effect of WASP-107b during a single transit with Keck/HIRES. We found the sky-projected inclination of WASP-107b's orbit, relative to its host s…
