Tidally Excited Oscillations in Heartbeat Binary Stars: Pulsation Phases and Mode Identification
Zhao Guo, Avi Shporer, Kelly Hambleton +1
Tidal forces in eccentric binary stars known as heartbeat stars excite detectable oscillations that shed light on the processes of tidal synchronization and circularization. We exa…
KIC 4142768: An Evolved Gamma Doradus/Delta Scuti Hybrid Pulsating Eclipsing Binary with Tidally Excited Oscillations
Zhao Guo, Jim Fuller, Avi Shporer +5
We present the characterization of KIC 4142768, an eclipsing binary with two evolved A-type stars in an eccentric orbit with a period of 14 days. We measure the fundamental paramet…
Two's a crowd? Characterising the effect of photometric contamination on the extraction of the global asteroseismic parameter in red-giant binaries
Sanjay Sekaran, Cole Johnston, Andrew Tkachenko +3
Theoretical scaling relations for solar-like oscillators and red giants are widely used to estimate fundamental stellar parameters. The accuracy and precision of these relations ha…
