3D hydro simulations demonstrate that donor central concentration (ρ_c/ρ_bar) controls inspiral morphology and mass-ejection history in common-envelope events for luminous red novae.
Black hole supernovae occur across a wide progenitor mass range from 19.5 to 60 solar masses, yielding final black hole masses of 3 to 26 solar masses that trend with but are not fully set by CO core mass.
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.
Presents a grid of 113 fast-rotating, chemically-homogeneous massive star models at Z=0.001 reaching core collapse with high angular momentum for use as supernova and GRB progenitors.
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.
Multi-D progenitor perturbations leave shock revival and explosion energetics essentially unchanged in 2D CHIMERA runs; any effects sit below the level of numerical stochasticity.
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.
Long-term 3D CCSN simulations of a low-mass iron-core progenitor show NS wind and multi-isotope decay heating create large plumes, asymmetric breakout, reverse-shock fragmentation, and ECSN-like yields unlike Cas A.
New MESA stellar tracks with varied winds and convective mixing produce a primary black hole mass function with twin peaks near 8 and 13 solar masses in most variations, the higher peak dominated by mass-ratio-reversal systems, with rates varying by a factor of six.
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.
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.
