Probing the wind and evolutionary state of the quiescent luminous blue variable Var2 in the Galaxy M33: constraints from self-consistent non-LTE modeling
A. Kostenkov, Y. Solovyeva, E. Dedov +2
Luminous Blue Variables (LBVs) are massive stars with extreme luminosities, exhibiting significant irregular photometric and spectroscopic variability. This paper is dedicated to t…
On the spatial distribution of luminous blue variables in the M33 galaxy
A. Kostenkov, S. Fabrika, A. Kaldybekova +6
In the current paper, we present a study of the spatial distribution of luminous blue variables (LBVs) and various LBV candidates (cLBVs) with respect to OB associations in the M33…
Optical Counterparts of Two Candidate Ultraluminous X-ray Sources in NGC 4536
H. Avdan, E. Sonbas, K. S. Dhuga +7
Archival {\it XMM-Newton}, {\it Chandra} and {\it Hubble Space Telescope (HST)} data have been used to study the X-ray and optical properties of two candidate ultraluminous X-ray s…
Search for LBVs in the Local Volume galaxies: study of four stars in NGC 4449
Y. Solovyeva, A. Vinokurov, A. Sarkisyan +8
We continue to search for LBV stars in galaxies outside the Local Group. In this work, we have investigated four luminous stars in NGC 4449. Multiple spectral observations carried…
Search for LBVs in the Local Volume galaxies: study of two stars in NGC 1156
Y. Solovyeva, A. Vinokurov, N. Tikhonov +7
We continue the search for luminous blue variables (LBVs) in Local Volume galaxies in order to study their fundamental parameters. In this paper, we report the discovery of two new…
Simultaneous X-ray/UV observations of ultraluminous X-ray source Holmberg II X-1 with Indian space mission AstroSat
A. Vinokurov, K. Atapin, O. P. Bordoloi +11
We present the results of 8 epochs of simultaneous UV and X-ray observations of the highly variable ultraluminous X-ray source (ULX) Holmberg II X-1 with AstroSat -- Indian multiwa…
