Wildly Oscillating Stars -- Unexplained dense ridge-like frequency agglomerations in A and F type pulsators
V. Antoci, J. Labadie-Bartz, M. Swiech +14
We investigate the origin of the dense, ridge-like frequency clusters observed in a subset of A and F type pulsating stars, which we refer to as `wildly oscillating' stars (WOS). T…
Discovery of the First Octupole Pulsation Mode in a delta Scuti Star: A Stationary l = 3 Sectoral Mode
S. A. Rappaport, R. Jayaraman, G. Handler +8
Aims. We are attempting to better understand how stellar pulsations in close binary systems are affected, and possibly induced, by tidal, Coriolis, and centrifugal forces. Methods.…
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…
HD 60435: The star that stopped pulsating
Donald W. Kurtz, Gerald Handler, Daniel L. Holdsworth +10
HD 60435 is a well-known rapidly oscillating (roAp) Ap star with a series of alternating even and odd degree modes, making it a prime asteroseismic target. It is also an oblique pu…
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…
