We present measurements of the dipole mode asymptotic period spacing (), the coupling factor between p- and g- modes (), the g-mode phase offset (), and the mixed-mod…
A close-in giant planet escapes engulfment by its star
Marc Hon, Daniel Huber, Nicholas Z. Rui +39
When main-sequence stars expand into red giants, they are expected to engulf close-in planets. Until now, the absence of planets with short orbital periods around post-expansion, c…

Asteroseismology of iota Draconis and Discovery of an Additional Long-Period Companion
Michelle L. Hill, Stephen R. Kane, Tiago L. Campante +25
Giant stars as known exoplanet hosts are relatively rare due to the potential challenges in acquiring precision radial velocities and the small predicted transit depths. However, t…

Asteroseismic Inference of Subgiant Evolutionary Parameters with Deep Learning
Marc Hon, Earl P. Bellinger, Saskia Hekker +2
With the observations of an unprecedented number of oscillating subgiant stars expected from NASA's TESS mission, the asteroseismic characterization of subgiant stars will be a vit…
Clumpiness: Time-domain classification of red-giant evolutionary states
James S. Kuszlewicz, Saskia Hekker, Keaton J. Bell
Long, high-quality time-series data provided by previous space-missions such as CoRoT and have made it possible to derive the evolutionary state of red-giant star…
Fast and Automated Peak Bagging with DIAMONDS (FAMED)
E. Corsaro, J. M. McKeever, J. S. Kuszlewicz
Stars of low and intermediate mass that exhibit oscillations may show tens of detectable oscillation modes each. Oscillation modes are a powerful to constrain the internal structur…
Age dating of an early Milky Way merger via asteroseismology of the naked-eye star Indi
William J. Chaplin, Aldo M. Serenelli, Andrea Miglio +81
Over the course of its history, the Milky Way has ingested multiple smaller satellite galaxies. While these accreted stellar populations can be forensically identified as kinematic…
