Dependences of radio pulsar parameters on the bimodal kick mode
Anton D. Lazarev, Sergei B. Popov
Analysis of observational data and theoretical modeling favors a bimodal distribution of the natal velocity kick of neutron stars. For normal isolated radio pulsars with…
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…
Planetary migration in wind-fed non-stationary accretion disks in binary systems
Alexey D. Nekrasov, Viacheslav V. Zhuravlev, Sergei B. Popov
An accretion disk can be formed around a secondary star in a binary system when the primary companion leaves the Main sequence and starts to lose mass at an enhanced rate. We study…
