Origin of Hyperion and Saturn's Rings in A Two-Stage Saturnian System Instability
Matija Ćuk, 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, Ondřej Pejcha, Tomek Kamiński +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…
Fates of Rotating Supergiants from Stellar Mergers and the Landscape of Transients upon Core-collapse
Daichi Tsuna, Jim Fuller, Wenbin Lu
We present a grid of rotating supergiant models from post-main sequence binary merger products, constructed by the MESA stellar evolution code. We focus on the evolution of these s…
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…
Multi-Phase Shock Cooling Emission in Ultra-Stripped Supernovae
Annastasia Haynie, Samantha C. Wu, Anthony L. Piro +1
Ultra-stripped and Type Ibn supernovae (USSNe and SNe Ibn, respectively) are fast-evolving, hydrogen-poor transients that often show signs of interaction with dense circumstellar m…
Transients by Black Hole Formation from Red Supergiants: Impact of Dense Circumstellar Matter
Daichi Tsuna, Xiaoshan Huang, Jim Fuller +1
Failed supernovae (SNe), which are likely the main channel for forming stellar-mass black holes, are predicted to accompany mass ejections much weaker than typical core-collapse SN…
