Low-frequency observations of low-mass binary systems with neutron star candidates
Elena Brylyakova, Marina Afonina, Gayane Tyul'basheva +2
Recently, astrometric and spectroscopic observations resulted in the discovery of several low-mass binaries with invisible components, which are expected to be compact objects. In…

Evolution of neutron stars in wide eccentric low-mass binary systems
Marina Afonina, Sergei Popov
Precise astrometric measurement with Gaia satellite resulted in the discovery of tens of wide binary systems consisting of a Sun-like star and an invisible component. The latter ca…

Probing the propeller regime with wide neutron star binaries
M. D. Afonina, S. B. Popov
We model the duration of the propeller stage in wide binary systems with neutron stars and calculate the time of accretion onset for various propeller models. We apply our modeling…
