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…
The Aligned Orbit of WASP-148b, the Only Known Hot Jupiter with a Nearby Warm Jupiter Companion, from NEID and HIRES
Xian-Yu Wang, Malena Rice, Songhu Wang +39
We present spectroscopic measurements of the Rossiter-McLaughlin effect for WASP-148b, the only known hot Jupiter with a nearby warm-Jupiter companion, from the WIYN/NEID and Keck/…
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…
Constraining the Orbit and Mass of epsilon Eridani b with Radial Velocities, Hipparcos IAD-Gaia DR2 Astrometry, and Multi-epoch Vortex Coronagraphy Upper Limits
Jorge Llop-Sayson, Jason J. Wang, Jean-Baptiste Ruffio +30
~Eridani is a young planetary system hosting a complex multi-belt debris disk and a confirmed Jupiter-like planet orbiting at 3.48 AU from its host star. Its age and architectur…
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…
TOI-532b: The Habitable-zone Planet Finder confirms a Large Super Neptune in the Neptune Desert orbiting a metal-rich M dwarf host
Shubham Kanodia, Gudmundur Stefansson, Caleb I. Canas +30
We confirm the planetary nature of TOI-532b, using a combination of precise near-infrared radial velocities with the Habitable-zone Planet Finder, TESS light curves, ground based p…
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…
Stellar Activity Manifesting at a One Year Alias Explains Barnard b as a False Positive
Jack Lubin, Paul Robertson, Gudmundur Stefansson +17
Barnard's star is among the most studied stars given its proximity to the Sun. It is often considered Radial Velocity (RV) standard for fully convective stars due to its RV s…
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…
