Modern tidal interaction models for rapid binary population synthesis: I. Methods
Veome Kapil, Ilya Mandel, Evgeni Grishin +3
In this work, we present an updated prescription of contemporary tidal dissipation theory adapted for rapid binary population synthesis. Our simplified expressions encode the depen…
Excitation and Damping of Oscillation Modes in Gaseous Planets
Jim Fuller, Marzia Parisi, Steve Markham +2
The excitation and damping mechanisms for oscillation modes of gas giant planets are undetermined. We show that differential rotation may greatly enhance convective viscosity in gi…
Origin of Hyperion and Saturn's Rings in A Two-Stage Saturnian System Instability
Matija Äuk, Maryame El Moutamid, Jim Fuller +1
The age of the rings and some of the moons of Saturn is an open question, and multiple lines of evidence point to a recent (few hundred Myr ago) cataclysm involving disruption of p…
Dynamical binary interactions in the 2040s
Nadejda Blagorodnova, OndÅej Pejcha, Tomek KamiÅski +15
Dynamical binary interactions such as common envelope (CE) evolution or stellar mergers are a critical phase in the formation of a wide variety of binary phenomena, ranging from bl…
Rapid binary mass transfer: Circumbinary outflows and angular momentum losses
Peter Scherbak, Wenbin Lu, Jim Fuller
High rates of stable mass transfer likely occur for some binary star systems, but the resulting flow of mass and angular momentum (AM) is unclear. We perform hydrodynamical simulat…
Circumstellar interaction in the extreme white dwarf merger remnant ZTF\,J1901+1458: A new class of white dwarf merger remnants with X-ray emission
Aayush Desai, Ilaria Caiazzo, Stephane Vennes +31
Double degenerate white dwarf (WD) mergers can exhibit extreme magnetic fields exceeding G and rapid rotation, but their spectral-energy distributions and high-energy emis…
