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…

Looking for Companionship: Radial Velocity Follow-Up of Lithium-Rich Giants with ESPRESSO
Maryum Sayeed, Andrew R. Casey, Benjamin T. Montet +4
Lithium-rich red giants have been a long-standing mystery in stellar astrophysics. A leading theory to explain these chemically peculiar and rare objects is interactions with a clo…
