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…
A massive white-dwarf merger product before final collapse
V. V. Gvaramadze, G. Gräfener, N. Langer +4
Gravitational wave emission can lead to the coalescence of close pairs of compact objects orbiting each other. For the case of neutron stars such mergers may yield masses above the…
New Luminous Blue Variable Candidates in NGC 4736
Y. Solovyeva, A. Vinokurov, S. Fabrika +8
We have found three new LBV candidates in the star-forming galaxy NGC 4736. They show typical well-known LBV spectra, broad and strong hydrogen lines, He I lines, many Fe II lines,…
Luminous Red Nova 2015 in the Galaxy M101
V. P. Goranskij, E. A. Barsukova, O. I. Spiridonova +8
We present the results of the study of the red nova PSN J14021678+5426205 based on the observations carried out with the Russian 6-m telescope (BTA) along with other telescopes of…
