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.
Post-processing of 44-year adiabatic 3D simulations of common envelope events yields lightcurves with a 3-5 year hot peak from photosphere expansion, dust formation after 1-3 years causing bolometric decline and 400 K plateau, plus predictions of optical thinning in 100-200 years, matching some obse
Binary evolution modeling constrains donor masses of 14-23 solar masses for two luminous red novae and shows dust masses are 1-5 orders of magnitude below total ejected envelope masses.
Interstellar objects may contribute enough baryonic mass to reduce the local dark matter halo density to 0.24 GeV/cm³.
Review of UV spectroscopy applications to hot evolved stars, emphasizing HST contributions and the need for continued observations ahead of HWO.
