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-…
Indication of rapid magnetic field decay in X-ray Dim Isolated Neutron Star RX J0720.4-3125
Andrei P. Igoshev, Sergei B. Popov
Magnetic field evolution of neutron stars is a long-standing debate. The rate of magnetic field decay for isolated, non-accreting neutron stars can be quantified by measuring the n…
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…
Probing the Propeller Regime with Symbiotic X-ray Binaries
M. D. Afonina, S. B. Popov
At the moment, there are two neutron star X-ray binaries with massive red supergiants as donors. De et al. (2023) proposed that the system SWIFT J0850.8-4219 contains a neutron sta…
Spin evolution of neutron stars
P. Abolmasov, A. V. Biryukov, S. B. Popov
In this paper we review the basics of magneto-rotational properties of neutron stars focusing on spin-up/spin-down behavior at different evolutionary stages. The main goal is to pr…
Observability of HOFNARs with SRG/eROSITA
A. D. Khokhriakova, A. I. Chugunov, S. B. Popov +2
Neutron stars can appear as sources of different nature. In this paper we address observability of a hypothetical class of neutron stars -- HOt and Fast Non Accreting Rotators, HOF…
Strange quark stars in binaries: formation rates, mergers and explosive phenomena
Grzegorz Wiktorowicz, Alessandro Drago, Giuseppe Pagliara +1
The existence of strange quark stars has been proposed many years ago. More recently, the possible co-existence of a first family composed of "normal" neutron stars with a second f…
