A nearly pristine star from the Large Magellanic Cloud
Alexander P. Ji, Vedant Chandra, Selenna Mejias-Torres +28
The first stars formed out of pristine gas, causing them to be so massive that none are expected to have survived until today. If their direct descendants were sufficiently low-mas…
The UV Legacy Library of Young Stars as Essential Standards (ULLYSES) Large Director's Discretionary Program with Hubble. I. Goals, Design, and Initial Results
Julia Roman-Duval, William J. Fischer, Alexander W. Fullerton +44
Specifically selected to leverage the unique ultraviolet capabilities of the Hubble Space Telescope, the Hubble Ultraviolet Legacy Library of Young Stars as Essential Standards (UL…
TESS Asteroseismic Masses and Radii of Red Giants with (and without) Planets
Myles Pope, Joleen K. Carlberg, Jeff Valenti +1
We present a study of asteroseismically derived surface gravities, masses, and radii of a sample of red giant stars both with and without confirmed planetary companions using TESS…
Lithium in Kepler Red Giants: Defining Normal and Anomalous
Jamie Tayar, Joleen K. Carlberg, Claudia Aguilera-Gómez +1
The orders of magnitude variation in lithium abundances of evolved stars have long been a puzzle. Diluted signals, ambiguous evolutionary states and unknown masses have made it cha…
Stellar multiplicity and stellar rotation: Insights from APOGEE
Christine Mazzola Daher, Carles Badenes, Jamie Tayar +18
We measure rotational broadening in spectra taken by the Apache Point Observatory Galactic Evolution Experiment (APOGEE) survey to characterise the relationship between stellar mul…
The Close Binary Fraction as a Function of Stellar Parameters in APOGEE: A Strong Anti-Correlation With Abundances
Christine N. Mazzola, Carles Badenes, Maxwell Moe +20
We use observations from the APOGEE survey to explore the relationship between stellar parameters and multiplicity. We combine high-resolution repeat spectroscopy for 41,363 dwarf…
