Pa 13 contains a detached double-degenerate binary of two hot pre-white dwarfs with dynamical masses 0.41 and 0.39 solar masses, offering the strongest evidence yet for planetary nebulae around post-RGB stars via either double-core evolution or CE-induced rejuvenation.

N-body modeling indicates Gaia BH3 formed as an exchange binary via dynamical interactions in the ED-2 progenitor cluster.
J2102-4145 shows one 0.375-solar-mass white dwarf retaining a thick hydrogen envelope via stable mass transfer and a 0.314-solar-mass companion with an extremely thin envelope below 10^{-7} solar masses after common-envelope ejection, challenging standard bifurcation criteria.
Simulations demonstrate that timescale-based decoupling predictions overestimate separations by a factor of ~3, velocity-based criteria are more accurate, and low-viscosity disks produce decreasing accretion that may identify LISA hosts.
SHARP is positioned to deliver the first statistical census of ultra-compact dual AGN, bridging kpc-scale pairs to sub-pc binary MBHs that emit gravitational waves.
Binary disruption and relaxation models explain the zone of avoidance and thermal eccentricities in S-star orbits around the Galactic center black hole.
PS16dtm is the tidal disruption of a 0.3 solar-mass star on a circular counter-rotating orbit inside the accretion disk of an NLS1 galaxy, hidden by a gaseous envelope from the observer's view.
MESA gains simultaneous binary star evolution, large nuclear networks, implicit hydrodynamics, and GYRE pulsation coupling for better massive star and supernova modeling.
