Modeling Stellar Oscillations and Granulation in Radial Velocity Time Series: A Fourier-based Method
Zhao Guo, Eric B. Ford, Dennis Stello +4
Tens of thousands of solar-like oscillating stars have been observed by space missions. Their photometric variability in the Fourier domain can be parameterized by a sum of two sup…
Warm Jupiters in TESS Full-Frame Images: A Catalog and Observed Eccentricity Distribution for Year 1
Jiayin Dong, Chelsea X. Huang, Rebekah I. Dawson +57
Warm Jupiters -- defined here as planets larger than 6 Earth radii with orbital periods of 8--200 days -- are a key missing piece in our understanding of how planetary systems form…
Detailed Characterization of Heartbeat Stars and their Tidally Excited Oscillations
Shelley J. Cheng, Jim Fuller, Zhao Guo +2
Heartbeat stars are a class of eccentric binary stars with short-period orbits and characteristic "heartbeat" signals in their light curves at periastron, caused primarily by tidal…
The effect of tides on near-core rotation: analysis of 35 Kepler Doradus stars in eclipsing and spectroscopic binaries
Gang Li, Zhao Guo, Jim Fuller +4
We systematically searched for gravity- and Rossby-mode period spacing patterns in Kepler eclipsing binaries with Doradus pulsators. These stars provide an excellent opportunit…
KIC 12268220: A Scuti Pulsating Star and an Active Protohelium White Dwarf in an Eclipsing Binary System
Kaiming Cui, Zhao Guo, Qing Gao +4
We present a photometric, spectroscopic, asteroseismic, and evolutionary analysis of the Algol-type eclipsing binary KIC 12268220. We find the O'Connell effect and anticorrelated e…
Tidal Asteroseismology: Possible Evidence of Non-linear Mode Coupling in an Equilibrium State in Kepler Eclipsing Binary KIC 3230227
Zhao Guo
Previously, a series of tidally-excited oscillations were discovered in the eccentric eclipsing binary KIC 3230227. The pulsation amplitudes and phases suggest the observed oscilla…
