Rapidly oscillating Ap stars observed with TESS. The LAMOST Ap sample and 49 Cam
Inês Rolo, Daniel L. Holdsworth, Margarida S. Cunha +4
The rapidly oscillating chemically peculiar A-type (roAp) stars offer valuable insights into the internal physical processes of all stars, but their study is challenged by their ra…
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…
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…
On the Existence of "Maia variables"
F. Kahraman Aliçavuş, G. Handler, S. Chowdhury +5
There are different classes of pulsating stars in the H-R diagram. While many of those classes are undisputed, some remain a mystery such as the objects historically called "Maia v…
Seven new triply eclipsing triple star systems
S. A. Rappaport, T. Borkovits, T. Mitnyan +19
We have identified nearly a hundred close triply eclipsing hierarchical triple star systems from data taken with the space telescope TESS. These systems are noteworthy in that we c…
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…
Transient Corotating Clumps Around Adolescent Low-Mass Stars From Four Years of TESS
Luke G. Bouma, Rahul Jayaraman, Saul Rappaport +5
Complex periodic variables (CPVs) are stars that exhibit highly structured and periodic optical light curves. Previous studies have indicated that these stars are typically disk-fr…
