  • Luminous blue variable candidates in M31 
    Sarkisyan A.; Sholukhova O.; Fabrika S.; Bizyaev D.; Valeev A.; Vinokurov A.; Solovyeva Y.; Kostenkov A.; Malanushenko V.; Nedialkov P. (2020)
    © 2020 The Author(s) Published by Oxford University Press on behalf of the Royal Astronomical Society. We study five luminous blue variable (LBV) candidates in the Andromeda galaxy and one more (MN112) in the Milky Way. ...
  • Modeling of Extended Atmospheres with Temperatures below 40000 K 
    Kostenkov A.; Vinokurov A.; Solovyeva Y.; Atapin K.; Fabrika S. (2020)
    © 2020, Pleiades Publishing, Ltd. Abstract: We calculate models of extended stellar atmospheres with a temperature in the range of 12 000–40 000 K and a mass loss rate of 10-6–10-4 Mʘyr-1. A large number of objects with ...
  • Modelling spectra of MN112 
    Kostenkov A.; Fabrika S.; Sholukhova O.; Sarkisyan A.; Bizyaev D. (2020)
    © 2020 The Author(s). MN112 is a Galactic luminous blue variable (LBV) candidate with a circumstellar nebula. P Cygni was the first LBV discovered, and was recorded during major eruptions in the 17th century. The stars ...
  • New luminous blue variable candidates in NGC 4736 
    Solovyeva Y.; Vinokurov A.; Fabrika S.; Kostenkov A.; Sholukhova O.; Sarkisyan A.; Valeev A.; Atapin K.; Spiridonova O.; Moskvitin A.; Nikolaeva E. (2019)
    © 2019 The Author(s). Published by Oxford University Press on behalf of the Royal Astronomical Society. We have found three new luminous blue variable (LBV) candidates in the star-forming galaxy NGC4736. They show typical ...
  • Search for LBVs in the Local Volume galaxies: Study of four stars in NGC 4449 
    Solovyeva Y.; Vinokurov A.; Sarkisyan A.; Kostenkov A.; Atapin K.; Fabrika S.; Oparin D.; Valeev A.; Bizyaev D.; Nedialkov P.; Spiridonova O. (2021)
    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 out for J122810.94+440540.6, J122811.70+440550.9, ...
  • SPEXTRA: Optimal extraction code for long-slit spectra in crowded fields 
    Sarkisyan A.; Vinokurov A.; Solovieva Y.; Sholukhova O.; Kostenkov A.; Fabrika S. (2017)
    © 2017, Pleiades Publishing, Ltd. We present a code for the optimal extraction of long-slit 2D spectra in crowded stellar fields. Its main advantage and difference from the existing spectrum extraction codes is the presence ...
