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 184743498: The First Tri-Axial Stellar Pulsator
Valencia Zhang, Saul Rappaport, Rahul Jayaraman +4
We have discovered a Scuti pulsator in a tight binary (P = 1.053 d) with nine pulsation modes whose frequencies are between 38 and 56 d. Each of these modes exhibits amp…
