Passage of a Gamma-Ray Burst Through a Molecular Cloud: The Absorption of its Afterglow in the X-ray Wavelength Range
Aleksandr Nesterenok
We study the absorption of a gamma-ray burst afterglow in a dense molecular cloud in the X-ray wavelength range. We report the results of numerical simulations of the propagation o…
4FGL J1544.22554: a new spider pulsar candidate
A. V. Karpova, S. V. Zharikov, D. A. Zyuzin +3
Context. Spider pulsars are millisecond pulsars in tight binary systems, in which a low-mass companion star is heated and ablated by the pulsar wind. Their observations allow one t…
Cooling of neutron stars in soft X-ray transients with realistic crust composition
A. Y. Potekhin, A. I. Chugunov, N. N. Shchechilin +1
Thermal radiation of neutron stars in soft X-ray transients (SXTs) in a quiescent state is believed to be powered by the heat deposited in the stellar crust due to nuclear reaction…
On variational trial functions in the extended Thomas-Fermi method
A. Y. Potekhin, A. I. Chugunov, N. N. Shchechilin +1
Parametrized nucleon density distributions are widely employed for the calculation of the properties of atomic nuclei and dense inhomogeneous matter in compact stars within the Tho…
Electrostatic energy of solid binary ionic mixtures
A. A. Kozhberov
We study the electrostatic energy of binary ionic mixtures (BIMs) in the form of Coulomb crystals with the main focus on ordered crystals. We consider 15 different binary bcc-like…
Terahertz Spin-Light Coupling in Proximitized Dirac Materials
Konstantin S. Denisov, Igor V. Rozhansky, Sergio O. Valenzuela +1
The two-dimensional (2D) materials are highly susceptible to the influence of their neighbors, thereby enabling the design by proximity phenomena. We reveal a remarkable terahertz…
