Simulations find nested bow shocks around an engulfed neutron star enhance drag force 10-100 times over Bondi-Hoyle-Lyttleton and allow force reversal based on envelope conditions.
The authors implement and validate nuclear networks coupled to GRRMHD with M1 neutrino transport in Gmunu, showing effects on core-collapse supernova shock revival and composition.
Neutrino-cooled collapsar disks in 3D GRMHD simulations lead to black hole equilibrium spins of a_eq ≈ 0.13, enabling 4-16x more powerful LGRB jets than non-radiative models.
3D simulations find that the convective Urca process reduces mixing efficiency near the convective boundary in a simmering white dwarf but does not restrict the overall size of the convection zone, with the A=23 pair having the largest effect.
3D simulations show the convective Urca process substantially reduces the convection zone size in a simmering white dwarf, though convection extends past the Urca shell.
Failed common envelope mergers yield 6-14 solar mass stripped stars consistent with long-lived core He-burning objects that appear single or in wide binaries from hierarchical triples.
MESA grid models find HD 20794 is a 0.80 solar-mass star aged ~9 Gyr whose observed abundances match core-collapse supernova enrichment and are preserved over Gyr timescales.
2D core-collapse supernova simulations of 15 solar-mass progenitors with varied multi-D initial structures show similar explosion dynamics, with no detectable impact from progenitor turbulence due to saturation by post-shock instabilities.
Jet-driven aspherical explosions improve fits to Perseus Cluster abundances and are necessary to explain zinc enrichment and other elemental trends in galactic stars and chemical evolution models.
Rotation produces only modest changes to blue loop luminosity and extent in MESA Cepheid models and cannot fix the mass discrepancy without substantial main-sequence overshooting.
Binary evolution simulations identify short (20-500 days) and long (2000-4000 days) orbital period ranges where massive star-black hole systems retain enough angular momentum for GRB jet production with negligible mass loss.
