A Test of Substellar Evolutionary Models with High-Precision Ages from Asteroseismology and Gyrochronology for the Benchmark System HR 7672AB
Yaguang Li, Michael C. Liu, Trent J. Dupuy +35
We present high-precision measurements for HR~7672AB, composed of a Sun-like (G0V) star and an L~dwarf companion. Three nights of precise (70 cm/s) radial velocity (RV) asteroseism…
K-dwarf Radius Inflation and a 10-Gyr Spin-down Clock Unveiled through Asteroseismology of HD 219134 from the Keck Planet Finder
Yaguang Li, Daniel Huber, J. M. Joel Ong +26
We present the first asteroseismic analysis of the K3\,V planet host HD~219134, based on four consecutive nights of radial velocities collected with the Keck Planet Finder. We appl…
Asteroseismology and Spectropolarimetry of the Exoplanet Host Star Serpentis
Travis S. Metcalfe, Derek Buzasi, Daniel Huber +31
The bright star Ser hosts a hot Neptune with a minimum mass of 13.6 and a 15.5 day orbit. It also appears to be a solar analog, with a mean rotation period of 25.8 d…
Flares Big and Small: a K2 and TESS View of ASAS-SN Superflares
Jesse Zeldes, Jason T. Hinkle, Benjamin J. Shappee +6
We investigate the flare-frequency distributions of 5 M-dwarfs that experienced superflares with energies in excess of erg detected by ASAS-SN. We use K2 and TESS short-c…
Comment on "The Sun is less active than other solar-like stars"
Travis S. Metcalfe, Jennifer van Saders
Reinhold et al. (Science, 1 May 2020, p. 518) provided two possible interpretations of measurements showing that the Sun is less active than other solar-like stars. We argue that o…
Chemical Evolution in the Milky Way: Rotation-based ages for APOGEE-Kepler cool dwarf stars
Zachary R. Claytor, Jennifer L. van Saders, Angela R. G. Santos +5
We use models of stellar angular momentum evolution to determine ages for stars in the APOGEE-\textit{Kepler} Cool Dwarfs sample. We focus on lower main-sequence stars, w…
