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…

The Discovery of Two Quadruple Star Systems with the Second and Third Shortest Outer Periods

Brian P. Powell, Guillermo Torres, Veselin B. Kostov +12

We present the discovery of two quadruple star systems -- TIC 285853156 and TIC 392229331 -- each consisting of two bound eclipsing binary stars. Among the most compact quadruples…

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…
