A phenomenological model of the magnetic field re-emergence in magnetars and discrepancy between the kinematic and characteristic ages
Rostislav D. Nikandrov, Sergei B. Popov
Robust age measurements for isolated neutron stars (NSs) are not easily available. That is why, often the characteristic age is used as a proxy. Here …

Disc accretion onto a binary black hole in a hierarchical triple system as an origin of the most luminous hyper-soft sources
Sergei B. Popov, Galina V. Lipunova
We propose that the recently discovered luminous hypersoft X-ray sources can be explained by accretion onto a binary black hole in a hierarchical triple system. For black hole mass…

Natal kicks of compact objects
Sergei Popov, Bernhard Müller, Ilya Mandel
When compact objects - neutron stars and black holes - are formed in a supernova explosion, they may receive a high velocity at formation, which may reach or even exceed 1000 km s-…
