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…
Discovery of 79 Scuti Stars in NGC 3532 Suggests a Decrease of Pulsator Occurrence with Age
Ian Berry, Daniel Huber, Yaguang Li +3
Many A-F type stars do not display Scuti pulsations, despite being located within the instability strip. Open clusters provide a unique opportunity to study Scuti pulsation…
Characterizing bright Scuti pulsators using TESS lightcurves
Prasad Mani, Timothy R. Bedding, Mara Bernizzoni +2
We present a study of bright, young Scuti stars near the zero-age main sequence using TESS light curves and Gaia DR3 data. From a sample of 2041 stars with G<7 and $G_{BP}-G_{R…
Unveiling the Sagittarius Dwarf Spheroidal Galaxy Core with Gaia DR3: A Red Clump Distance Precise to 2%
Ellie K. H. Toguchi-Tani, Daniel R. Hey, Thomas de Boer +2
The Sagittarius dwarf spheroidal galaxy provides us with the unique opportunity to study an ongoing Galactic cannibalistic event between our Milky Way Galaxy and a satellite dwarf…
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 of the red giant companions to Gaia BH2 and BH3
Daniel Hey, Yaguang Li, Joel Ong
The stellar companions in the binary black hole systems Gaia BH2 and BH3, both of which are -enhanced red giant branch stars, are expected to show normal modes with the characte…
