Excitation of Inertial Modes in 3D Simulations of Rotating Convection in Planets and Stars
J. R. Fuentes, Ankit Barik, Jim Fuller
Thermal convection in rotating stars and planets drives anisotropic turbulence and differential rotation, both capable of feeding energy into global oscillations. Using 3D simulati…
Anomalously fast core and envelope rotation in red giants
Siddharth Dhanpal, Othman Benomar, Shravan Hanasoge +1
Red giants undergo dramatic and complex structural transformations as they evolve. Angular momentum is transported between the core and envelope during this epoch, a poorly underst…
Asteroseismology with TESS: Emergence of Dipole Mode Suppression From Subgiants?
Shurui Lin, Tanda Li, Shude Mao +1
Dipole mode suppression is an observed behavior of solar-like oscillations in evolved stars. This study aims to search for depressed dipole modes in giant stars using data from the…
Expansion properties of the young supernova type Iax remnant Pa 30 revealed
Tim Cunningham, Ilaria Caiazzo, Nikolaus Z. Prusinski +14
The recently discovered Pa 30 nebula, the putative type Iax supernova remnant associated with the historical supernova of 1181 AD, shows puzzling characteristics that make it uniqu…
Tidal Spin-up of Subdwarf B Stars
Linhao Ma, Jim Fuller
Hot subdwarf B (sdB) stars are stripped helium-burning stars that are often found in close binaries, where they experience strong tidal interactions. The dissipation of tidally exc…
Ultrashort-period WD binaries are not undergoing strong tidal heating
Peter Scherbak, Jim Fuller
Double white dwarf (WD) binaries are increasingly being discovered at short orbital periods where strong tidal effects and significant tidal heating signatures may occur. We assume…
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…
Slowly Rotating Close Binary Stars in Cassini States
Catherine Felce, Jim Fuller
Recent asteroseismic measurements have revealed a small population of stars in close binaries, containing primaries with extremely slow rotation rates. Such stars defy the standard…
Super Slowly Spinning Stars in Close Binaries
Jim Fuller, Catherine Felce
Stars in short-period binaries typically have spins that are aligned and synchronized with the orbit of their companion. In triple systems, however, the combination of spin and orb…
Wide post-common envelope binaries containing ultramassive white dwarfs: evidence for efficient envelope ejection in massive AGB stars
Natsuko Yamaguchi, Kareem El-Badry, Jim Fuller +7
Post-common-envelope binaries (PCEBs) containing a white dwarf (WD) and a main-sequence (MS) star can constrain the physics of common envelope evolution and calibrate binary evolut…
