The Effect of Different Methods for Accounting for -enhancement on the Asteroseismic Modeling of Metal-Poor Stars
Christopher J. Lindsay, J. M. Joel Ong, Sarbani Basu +2
Constraining stellar models using asteroseismic and spectroscopic observations is a powerful method for precisely determining the fundamental properties of stars in different kinem…
Stellar Models are Reliable at Low Metallicity: An Asteroseismic Age for the Ancient Very Metal-Poor Star KIC 8144907
Daniel Huber, Ditte Slumstrup, Marc Hon +15
Very metal-poor stars ([Fe/H]<-2) are important laboratories for testing stellar models and reconstructing the formation history of our galaxy. Asteroseismology is a powerful tool…
Verification of Gaia DR3 Single-lined Spectroscopic Binary Solutions With Three Transiting Low-mass Secondaries
Stephen P. Schmidt, Kevin C. Schlaufman, Keyi Ding +18
While secondary mass inferences based on single-lined spectroscopic binary (SB1) solutions are subject to degeneracies, this degeneracy can be lifted through the observat…
Three low-mass companions around aged stars discovered by TESS
Zitao Lin, Tianjun Gan, Sharon X. Wang +42
We report the discovery of three transiting low-mass companions to aged stars: a brown dwarf (TOI-2336b) and two objects near the hydrogen burning mass limit (TOI-1608b and TOI-252…
Spinning up the Surface: Evidence for Planetary Engulfment or Unexpected Angular Momentum Transport?
Jamie Tayar, Facundo D. Moyano, Melinda Soares-Furtado +15
In this paper, we report the potential detection of a nonmonotonic radial rotation profile in a low-mass lower-luminosity giant star. For most low- and intermediate-mass stars, the…
TESS asteroseismology of the Kepler red giants
Dennis Stello, Nicholas Saunders, Sam Grunblatt +11
Red giant asteroseismology can provide valuable information for studying the Galaxy as demonstrated by space missions like CoRoT and Kepler. However, previous observations have bee…
Age-Dating Red Giant Stars Associated with Galactic Disk and Halo Substructures
Samuel K. Grunblatt, Joel C. Zinn, Adrian M. Price-Whelan +12
The vast majority of Milky Way stellar halo stars were likely accreted from a small number (3) of relatively large dwarf galaxy accretion events. However, the timing of t…
Astraea: Predicting Long Rotation Periods with 27-Day Light Curves
Yuxi, Lu, Ruth Angus +5
The rotation periods of planet-hosting stars can be used for modeling and mitigating the impact of magnetic activity in radial velocity measurements and can help constrain the high…
Interferometric diameters of five evolved intermediate-mass planet-hosting stars measured with PAVO at the CHARA Array
T. R. White, D. Huber, A. W. Mann +8
Debate over the planet occurrence rates around intermediate-mass stars has hinged on the accurate determination of masses of evolved stars, and has been exacerbated by a paucity of…
The masses of retired A stars with asteroseismology: Kepler and K2 observations of exoplanet hosts
Thomas S. H. North, Tiago L. Campante, Andrea Miglio +7
We investigate the masses of "retired A stars" using asteroseismic detections on seven low-luminosity red-giant and sub-giant stars observed by the NASA Kepler and K2 Missions. Our…
