The study of AF And. I. Hydrogen abundance constraints and dynamically-consistent wind model of the hot state
E. O. Dedov, A. E. Kostenkov, A. S. Vinokurov +1
This paper starts a series of works devoted to an in-depth study of luminous blue variable AF And in the M31 galaxy. Here we present the results of non-LTE modelling of the star in…

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…
