NGC 1901: A new benchmark cluster for gyrochronology in the TESS Southern continuous viewing zone
Mara Bernizzoni, Timothy R. Bedding, Prasad Mani +5
We use Gaia DR3 astrometry and TESS time-series photometry to study NGC 1901, a sparse open cluster in the TESS Southern continuous viewing zone, that has been neglected due to its…
The Pan-Pacific Planet Search -- IX. A menagerie of companions orbiting evolved stars
Robert A. Wittenmyer, Alexander Venner, Tyler Fairnington +22
We present resolutions as to the nature of six speculative candidate companions proposed in the final data release of the Pan-Pacific Planet Search, a 6-year radial-velocity survey…
TESS Observations of Stochastic Low-frequency Variability in Extreme Helium Stars
Courtney L. Crawford, C. Simon Jeffery, May G. Pedersen +4
Extreme helium stars (EHes) are low-mass hydrogen-deficient stars thought to be the products of double white dwarf mergers. Despite prolonged ground-based observations, there is no…
CHARA Interferometry and TESS Asteroseismology of the Core-Helium Burning Red Giant Cyg
Arnab Chowhan, Timothy R. Bedding, Daniel Huber +5
We present a detailed study of the secondary red clump star, Cyg, by combining long-baseline visible interferometry using the PAVO beam combiner at the CHARA Array with high-pr…
Asteroseismic Diagnostics for Red Giants with Kepler: Measuring epsilon and Small Frequency Separations in 16,000 Stars
Yingxiang Wang, Timothy R. Bedding, Yaguang Li +4
Asteroseismic studies of red giants have primarily relied on two global parameters: the large frequency separation (Dnu) and the frequency of maximum power (numax). Meanwhile, the…
Testing Red Clump Models with the Asteroseismic Binary KIC 10841730
Lea S. Schimak, Timothy R. Bedding, Courtney L. Crawford +9
Binaries in which both stars are pulsating are rare but extremely valuable. We present the first study of an asteroseismic binary system consisting of a core helium-burning red clu…
