Observations of ultraluminous X-ray sources with the 6-m telescope of the SAO RAS
A. Vinokurov, K. Atapin, Y. Solovyeva +2
The nature of ultraluminous X-ray sources (ULXs) is not yet fully understood but it can be done in the most efficient way by analyzing its optical emission and environment. We pres…
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.…
Optical Counterpart to the Ultraluminous X-Ray Source in the UGC6456 Galaxy
Alexander Vinokurov, Kirill Atapin, Yulia Solovyeva
We report the identification of the optical counterpart to the transient ultraluminuos X-ray source in the blue dwarf galaxy UGC6456 (VII Zw 403). The source is highly variable in…
