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-p…
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…
Kepler meets Gaia DR3: homogeneous extinction-corrected color-magnitude diagram and binary classification
D. Godoy-Rivera, S. Mathur, R. A. GarcÃa +8
The original Kepler mission has delivered unprecedented high-quality photometry. These data have impacted numerous research fields (e.g., asteroseismology and exoplanets), and cont…
Improving the stellar age determination through joint modeling of binarity and asteroseismology -- Grid modeling of the seismic red-giant binary KIC 9163796
D. H. Grossmann, P. G. Beck, S. Mathur +12
Context. Typical uncertainties of ages determined for single star giants from isochrone fitting using single-epoch spectroscopy and photometry without any additional constraints ar…
