The eruptive young star IRAS 21204+4913
M. A. Burlak, A. V. Dodin, A. V. Zharova +7
The results of photometric, polarimetric, and spectroscopic observations are presented for the young star IRAS 21204+4913, whose visible brightness has increased by $\approx 5^{\rm…
On the causes of brightness variability of the young star BP Tau
M. A. Burlak, K. N. Grankin, A. V. Dodin +6
We have constructed and analysed the secular light curve of BP Tau, a classical T Tauri-type star. Wave-like variations in the average brightness were detected, with an amplitude o…
ZZ Tau IRS: a low mass UX Ori type star with strong wind
M. A. Burlak, A. V. Dodin, A. V. Zharova +7
The results of photometric, polarimetric and spectroscopic observations of the young star ZZ Tau IRS in the visible and near-infrared bands are presented. Against the continuum of…
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…
Photometry and spectroscopy of SN 2015bh in the galaxy NGC 2770
V. P. Goranskij, E. A. Barsukova, A. F. Valeev +4
We present medium-resolution spectroscopy and multicolor photometry for the optical transient PSN J09093496+3307204 (SN 2015bh) in the galaxy NGC 2770, which has transferred into t…
Orbital motions and light curves of young binaries XZ Tau and VY Tau
A. V. Dodin, N. V. Emelyanov, A. V. Zharova +3
The results of our speckle interferometric observations of young binaries VY Tau and XZ Tau are presented. For the first time, we found a relative displacement of VY Tau components…
Var C: Long-term photometric and spectral variability of an LBV in M33
B. Burggraf, K. Weis, D. J. Bomans +6
So far the highly unstable phase of luminous blue variables (LBVs) has not been understood well. It is still uncertain why and which massive stars enter this phase. Investigating t…
Spectral Variability of LBV star V532 (Romano's star)
O. N. Sholukhova, S. N. Fabrika, A. V. Zharova +2
(abridged) We present the results of studying the spectral and photometric variability of the luminous blue variable star V532 in M33. The photometric variations are traced from 19…
GSC 2576-02071 and GSC 2576-01248: two Algol-type eclipsing binaries studied using CCD observations and historical photographic data
K. V. Sokolovsky, S. V. Antipin, A. V. Zharova +1
An initial investigation of two poorly studied eclipsing binaries separated by ~3' in the sky is presented. The first star (GSC 2576-01248) was discovered by the TrES exoplanet sea…
The progenitor and remnant of the helium nova V445 Puppis
V. P. Goranskij, S. Yu. Shugarov, A. V. Zharova +2
V445 Pup was a peculiar nova with no hydrogen spectral lines during the outburst. The spectrum contained strong emission lines of carbon, oxygen, calcium, sodium, and iron. We have…
MN112: a new Galactic candidate Luminous Blue Variable
V. V. Gvaramadze, A. Y. Kniazev, S. Fabrika +4
We report the discovery of a new Galactic candidate Luminous Blue Variable (cLBV) via detection of an infrared circular nebula and follow-up spectroscopy of its central star. The n…
