NGC 5474 X-1: a neutron star ULX in an old stellar cluster?
Kirill Atapin, Alexander Vinokurov, Arkadiy Sarkisyan +4
We present the optical and X-ray study of the ultraluminous X-ray source (ULX) NGC 5474 X-1. The X-ray spectrum taken during the bright state of the source ($L_X \sim 2\times10^{40…
Determining parameters of ULXs with model grids of extended atmospheres
A. Kostenkov, A. Vinokurov, Y. Solovyeva
In current work we continued study of wind parameters of ultraluminous X-ray sources (ULXs) using model grids of extended atmospheres. We present sets of models with temperatures f…
Modeling spectra of MN112
A. Kostenkov, S. Fabrika, O. Sholukhova +2
MN112 is the Galactic luminous blue variable (LBV) candidate with circumstellar nebula. P Cygni is the first discovered LBV, which was recorded during major eruptions in the 17th c…
Luminous Blue Variable candidates in M31
A. Sarkisyan, O. Sholukhova, S. Fabrika +7
We study five Luminous Blue Variable (LBV) candidates in the Andromeda galaxy and one more (MN112) in the Milky Way. We obtain the same-epoch near-infrared (NIR) and optical spectr…
Modeling of extended atmospheres with temperatures below 40000K
A. Kostenkov, A. Vinokurov, Y. Solovyeva +2
We calculate models of extended stellar atmospheres with a temperature in the range of 12000-40000K and a mass loss rate of yr. A large number of…
