Pushing the Limit of Asteroseismic Detection for Cool Dwarfs using TESS and Deep Learning
Waly M Z Karim, Rocio Kiman, Derek Buzasi +6
Asteroseismology provides a powerful probe of stellar interiors by detecting stellar oscillations, including solar-like oscillations, which are stochastically excited by near-surfa…
EL CMi: confirmation of triaxial pulsation theory
G. Handler, S. A. Rappaport, D. Jones +10
Triaxial pulsators are a recently discovered group of oscillating stars in close binary systems that show pulsations around three axes at the same time. It has recently been theore…
Tidally distorted stars are triaxial pulsators
Jim Fuller, Saul Rappaport, Rahul Jayaraman +2
Stars in close binaries are tidally distorted, and this has a strong effect on their pulsation modes. We compute the mode frequencies and geometries of tidally distorted stars usin…
TIC 435850195: The Second Tri-Axial, Tidally Tilted Pulsator
Rahul Jayaraman, Saul Rappaport, Brian Powell +8
The Transiting Exoplanet Survey Satellite (TESS) has enabled the discovery of numerous tidally tilted pulsators (TTPs), which are pulsating stars in close binaries where the presen…
Non-linear Three-mode Coupling of Gravity Modes in Rotating Slowly Pulsating B Stars: Stationary Solutions and Modeling Potential
Jordan Van Beeck, Tim Van Hoolst, Conny Aerts +1
Context. Slowly pulsating B (SPB) stars display multi-periodic variability in the gravito-inertial mode regime with indications of non-linear resonances between modes. Several have…
Tidally Trapped Pulsations in Binary Stars
J. Fuller, D. W. Kurtz, G. Handler +1
A new class of pulsating binary stars was recently discovered, whose pulsation amplitudes are strongly modulated with orbital phase. Stars in close binaries are tidally distorted,…
Tidally Trapped Pulsations in a close binary star system discovered by TESS
G. Handler, D. W. Kurtz, S. A. Rappaport +12
It has long been suspected that tidal forces in close binary stars could modify the orientation of the pulsation axis of the constituent stars. Such stars have been searched for, b…
Lupi: measuring the heartbeat of a doubly-magnetic massive binary with BRITE-Constellation
H. Pablo, M. Shultz, J. Fuller +15
Lupi A is a binary system consisting of two main sequence early B-type stars Aa and Ab in a short period, moderately eccentric orbit. The close binary pair is the onl…
On the sensitivity of gravito-inertial modes to differential rotation in intermediate-mass main-sequence stars
T. Van Reeth, J. S. G. Mombarg, S. Mathis +9
Context. While rotation has a major impact on stellar structure and evolution, its effects are not well understood. Thanks to high- quality and long timebase photometric observatio…
HD 183648: a Kepler eclipsing binary with anomalous ellipsoidal variations and a pulsating component
T. Borkovits, A. Derekas, J. Fuller +16
KIC 8560861 (HD 183648) is a marginally eccentric (e=0.05) eclipsing binary with an orbital period of P_orb=31.973d, exhibiting mmag amplitude pulsations on time scales of a few da…
KIC 4544587: an Eccentric, Short Period Binary System with delta Sct Pulsations and Tidally Excited Modes
K. M. Hambleton, D. W. Kurtz, A. Prsa +7
We present Kepler photometry and ground based spectroscopy of KIC 4544587, a short-period eccentric eclipsing binary system with self-excited pressure and gravity modes, tidally ex…
