Oscillation Frequencies of Moderately Rotating Delta Scuti Stars: Asymmetric Mode Splittings Due to Non-spherical Distortion
Zhao Guo, Timothy R. Bedding, A. A. Pamyatnykh +5
We find that the observed pressure-mode rotational splittings of slowly/moderately rotating Delta Scuti stars and Beta Cephei stars mostly have a positive asymmetry. That is, the l…
Pulsation Phases and Mode Identification of Tidally Excited Oscillations in Fourteen Kepler Heartbeat Stars
Min-Yu Li, Sheng-Bang Qian, Li-Ying Zhu +6
Tidally excited oscillations (TEOs) in Heartbeat Stars (HBSs) are an essential probe of the internal properties of the systems, but their potential has yet to be fully exploited. B…
gyre_tides: Modeling binary tides within the gyre stellar oscillation code
Meng Sun, R. H. D. Townsend, Zhao Guo
We describe new functionality in the GYRE stellar oscillation code for modeling tides in binary systems. Using a multipolar expansion in space and a Fourier-series expansion in tim…
Rotation and pulsation in Ap stars: first light results from TESS sectors 1 and 2
M. S. Cunha, V. Antoci, D. L. Holdsworth +36
We present the first results from the Transiting Exoplanet Survey Satellite (TESS) on the rotational and pulsational variability of magnetic chemically peculiar A-type stars. We an…
A Young Eclipsing Binary and its Luminous Neighbors in the Embedded Star Cluster Sh 2-252E
Kathryn V. Lester, Douglas R. Gies, Zhao Guo
We present a photometric and light curve analysis of an eccentric eclipsing binary in the K2 Campaign 0 field that resides in Sh 2-252E, a young star cluster embedded in an H II re…
KIC 8262223: A Post-Mass Transfer Eclipsing Binary Consisting of a Delta Scuti Pulsator and a Helium White Dwarf Precursor
Zhao Guo, Douglas R. Gies, Rachel A. Matson +3
KIC~8262223 is an eclipsing binary with a short orbital period ( d). The {\it Kepler} light curves are of Algol-type and display deep and partial eclipses, ellipsoidal vari…
