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…
Search and Study of the Brightest Stars in the Galaxy IC 342
O. N. Sholukhova, N. A. Tikhonov, Y. N. Solovyeva +7
We have selected candidate massive stars in the galaxy IC 342 based on archival images from the Hubble Space Telescope and images from the 2 m telescope at the Natioal Astronomical…
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…
New data for the LBV in NGC 4736
Y. Solovyeva, A. Vinokurov, A. Kostenkov +3
We present new spectral and photometric data of confirmed LBV star from the NGC4736 galaxy. The star NGC4736_1 (Mbol = -11.5 mag) showed noticeable spectral variability from 2015 t…
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…
New luminous blue variable candidates in the NGC 247 galaxy
Y. Solovyeva, A. Vinokurov, A. Sarkisyan +6
We search for LBV stars in galaxies outside the Local Group. Here we present a study of two bright sources in the NGC 247 galaxy. Object j004703.27-204708.4 ($M_V=-9.08 \pm 0.…
