The California Legacy Survey V. Chromospheric Activity Cycles in Main Sequence Stars

Howard Isaacson, Andrew W. Howard, Benjamin Fulton +31

We present optical spectroscopy of 710 solar neighborhood stars collected over twenty years to catalog chromospheric activity and search for stellar activity cycles. The California…

The TESS-Keck Survey XX: 15 New TESS Planets and a Uniform RV Analysis of all Survey Targets

Alex S. Polanski, Jack Lubin, Corey beard +69

The Transiting Exoplanet Survey Satellite (TESS) has discovered hundreds of new worlds, with TESS planet candidates now outnumbering the total number of confirmed planets from $\te…

The TESS-Keck Survey. XXII. A sub-Neptune Orbiting TOI-1437

Daria Pidhorodetska, Emily A. Gilbert, Stephen R. Kane +40

Exoplanet discoveries have revealed a dramatic diversity of planet sizes across a vast array of orbital architectures. Sub-Neptunes are of particular interest; due to their absence…

Metallicities and Refined Stellar Parameters for 52 Cool Dwarfs with Transiting Planets and Planet Candidates

Rebecca Gore, Steven Giacalone, Courtney D. Dressing +8

We collected near-infrared spectra of 65 cool stars with the NASA InfraRed Telescope Facility (IRTF) and analyze them to calculate accurate metallicities and stellar parameters. Th…

The TESS-Keck Survey. XII. A Dense 1.8 R Ultra-Short-Period Planet Possibly Clinging to a High-Mean-Molecular-Weight Atmosphere After the First Gyr

Ryan A. Rubenzahl, Fei Dai, Andrew W. Howard +39

The extreme environments of ultra-short-period planets (USPs) make excellent laboratories to study how exoplanets obtain, lose, retain, and/or regain gaseous atmospheres. We presen…

The TESS-Keck Survey. XVIII. A sub-Neptune and spurious long-period signal in the TOI-1751 system

Anmol Desai, Emma V. Turtelboom, Caleb K. Harada +37

We present and confirm TOI-1751 b, a transiting sub-Neptune orbiting a slightly evolved, solar-type, metal-poor star ( K, , V = 9.3 ma…
