Disrupted dense star clusters release ~300,000 white dwarf, 150,000 black hole, and 1,000 neutron star binaries into the Milky Way, but Gaia DR3/DR4 detect only a handful of white dwarf systems with none for the others.

abstract
The evolution of a binary star system by various analytic approximations of mass transfer is discussed, with particular attention payed to the stability of these processes against runaway on the thermal and dynamical timescales of the mass donating star. Mass transfer in red giant - neutron star binary systems is used as a specific example of such mass transfer, and is investigated. Hjellming and Webbink's (1987) results on the dynamic timescale response of a convective star with a core to mass loss are applied, with new results. It is found that mass transfer is usually stable, so long as the the wind's specific angular momentum does not exceed the angular momentum per reduced mass of the system. This holds for both dynamical and thermal timescales. Those systems which are not stable will usually transfer mass on the thermal timescale. Included are graphs illustrating the variation of the Roche radius exponent with mass ratio in the binary, for various parameters in the non-conservative mass transfer, as well as evolutionary paths of interacting red giant neutron star binaries.

A parametrized analytical model for BBH mass ratios from the stable mass transfer channel is derived and applied to the 10 solar-mass peak in GWTC-4, favoring little mass-ratio reversal.
Stable mass transfer produces two distinct peaks in merging binary black hole primary mass and mass ratio distributions via mass ratio reversal under conservative mass transfer.
Simulations across mass transfer rates from 10^-5 to 10^-1 solar masses per year find that radiatively cooled binaries develop equatorially concentrated L2 outflows and increasing cooling luminosity at high rates.
Adiabatic mass-loss models for massive helium stars give critical mass ratios 0.7-3.0 on the main sequence and 1.5-27 on the Hertzsprung gap, lowered by winds and adjusted by isotropic re-emission.
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.
Simulations overpredict hot subdwarf and RR Lyrae binaries with Gaia astrometric solutions but match red clump stars with high mass functions as potential black hole impostors, implying fewer au-scale RR Lyrae binaries than expected.
A synthesis of observational data on red novae as stellar merger events, including outburst properties, progenitor diversity, and long-term remnants.
