Planet Masses, Radii, and Orbits from NASA's K2 Mission
Andrew W. Howard, Evan Sinukoff, Sarah Blunt +50
We report the masses, sizes, and orbital properties of 86 planets orbiting 55 stars observed by NASA's K2 Mission with follow-up Doppler measurements by the HIRES spectrometer at t…
Asteroseismology of the Nearby K-Dwarf Draconis using the Keck Planet Finder and TESS
Marc Hon, Daniel Huber, Yaguang Li +76
Asteroseismology of dwarf stars cooler than the Sun is very challenging due to the low amplitudes and rapid timescales of oscillations. Here, we present the asteroseismic detection…
TESS Giants Transiting Giants. VI. Newly Discovered Hot Jupiters Provide Evidence for Efficient Obliquity Damping after the Main Sequence
Nicholas Saunders, Samuel K. Grunblatt, Ashley Chontos +53
The degree of alignment between a star's spin axis and the orbital plane of its planets (the stellar obliquity) is related to interesting and poorly understood processes that occur…
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…
Planet Hunters TESS V: a planetary system around a binary star, including a mini-Neptune in the habitable zone
Nora L. Eisner, Samuel K. Grunblatt, Oscar Barragán +61
We report on the discovery and validation of a transiting long-period mini-Neptune orbiting a bright (V = 9.0 mag) G dwarf (TOI 4633; R = 1.05 RSun, M = 1.10 MSun). The planet was…
A Tale of Two Peas-In-A-Pod: The Kepler-323 and Kepler-104 Systems
C. Alexander Thomas, Lauren M. Weiss, Howard Isaacson +10
In order to understand the relationship between planet multiplicity, mass, and composition, we present newly measured masses of five planets in two planetary systems: Kepler-323 an…
