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…
The California Legacy Survey III. On The Shoulders of (Some) Giants: The Relationship between Inner Small Planets and Outer Massive Planets
Lee J. Rosenthal, Heather A. Knutson, Yayaati Chachan +11
We use a high-precision radial velocity survey of FGKM stars to study the conditional occurrence of two classes of planets: close-in small planets (0.023--1 au, 2--30 Earth masses)…
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…
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…
The California Legacy Survey I. A Catalog of 178 Planets from Precision Radial Velocity Monitoring of 719 Nearby Stars over Three Decades
Lee J. Rosenthal, Benjamin J. Fulton, Lea A. Hirsch +20
We present a high-precision radial velocity (RV) survey of 719 FGKM stars, which host 164 known exoplanets and 14 newly discovered or revised exoplanets and substellar companions.…
Confirmation of the Long-Period Planet Orbiting Gliese 411 and the Detection of a New Planet Candidate
Spencer A. Hurt, Benjamin Fulton, Howard Isaacson +4
We perform a detailed characterization of the planetary system orbiting the bright, nearby M dwarf Gliese 411 using radial velocities gathered by APF, HIRES, SOPHIE, and CARMENES.…
Giant Outer Transiting Exoplanet Mass (GOT 'EM) Survey. II. Discovery of a Failed Hot Jupiter on a 2.7 Year, Highly Eccentric Orbit
Paul A. Dalba, Stephen R. Kane, Zhexing Li +13
Radial velocity (RV) surveys have discovered giant exoplanets on au-scale orbits with a broad distribution of eccentricities. Those with the most eccentric orbits are valuable labo…
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…
The California Legacy Survey II. Occurrence of Giant Planets Beyond the Ice line
Benjamin J. Fulton, Lee J. Rosenthal, Lea A. Hirsch +20
We used high-precision radial velocity measurements of FGKM stars to determine the occurrence of giant planets as a function of orbital separation spanning 0.03-30 au. Giant planet…
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…
Long Period Jovian Tilts the Orbits of Two sub-Neptunes Relative to Stellar Spin Axis in Kepler-129
Jingwen Zhang, Lauren M. Weiss, Daniel Huber +10
We present the discovery of Kepler-129 d ( yr, , ) based on six years of radial v…
Dust-Enshrouded AGN can Dominate Host-Galaxy-Scale Cold-Dust Emission
Jed McKinney, Christopher C. Hayward, Lee J. Rosenthal +4
It is widely assumed that long-wavelength infrared (IR) emission from cold dust (T~20-40K) is a reliable tracer of star formation even in the presence of a bright active galactic n…
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…
