Solving puzzles of GW150914 by primordial black holes
S. Blinnikov, A. Dolgov, N. K. Porayko +1
The black hole binary properties inferred from the LIGO gravitational wave signal GW150914 posed several serious problems. The high masses and low effective spin of black hole bina…
Discovery and Modeling of a Flattening of the Positive Cyclotron Line/Luminosity Relation in GX 304-1 with RXTE
Richard E. Rothschild, Matthias Kuehnel, Katja Pottschmidt +8
The RXTE observed four outbursts of the accreting X-ray binary transient source, GX 304-1 in 2010 and 2011. We present results of detailed 3-100 keV spectral analysis of 69 separat…
A propelling neutron star in the enigmatic Be-star ~Cassiopeia
K. Postnov, L. Oskinova, J. M. Torrejón
The enigmatic X-ray emission from the bright optical star, Cassiopeia, is a long-standing problem. Cas is known to be a binary system consisting of a Be-type star and a low…
Convection in axially symmetric accretion discs with microscopic transport coefficients
K. L. Malanchev, K. A. Postnov, N. I. Shakura
The vertical structure of stationary thin accretion discs is calculated from the energy balance equation with heat generation due to microscopic ion viscosity η and electron heat c…
NuSTAR observations of the supergiant X-ray pulsar IGR J18027-2016: accretion from the stellar wind and possible cyclotron absorption line
A. Lutovinov, S. Tsygankov, K. Postnov +3
We report on the first focused hard X-ray view of the absorbed supergiant system IGRJ18027-2016 performed with the NuSTAR observatory. The pulsations are clearly detected with a pe…
Rapidly rotating neutron star progenitors
K. A. Postnov, A. G. Kuranov, D. A. Kolesnikov +2
Rotating proto-neutron stars can be important sources of gravitational waves to be searched for by present-day and future interferometric detectors. It was demonstrated by Imshenni…
