Apsidal motion and physical parameters in the eclipsing system V490 Sct
I. M. Volkov, A. S. Kravtsova
We report long-termed UBVRIRcIc photometry of the highly eccentric 12.04 day detached eclipsing binary V490 Sct (V =13.1, B9.5+A0, e = 0.40), which we use to determine its relative…
BU CMi as a quadruple doubly eclipsing system
I. M. Volkov, A. S. Kravtsova, D. Chochol
We found that the known spectroscopic binary and variable BU~CMi = HD65241 (=6.4-6.7 mag, Sp~=~A0~V) is a quadruple doubly eclipsing 2+2 system. Both eclipsing binaries are deta…
Absolute parameters and period variation in a semidetached eclipsing variable V2247 Cyg
M. A. Burlak, I. M. Volkov, N. P. Ikonnikova
We aim to determine the absolute parameters of the components of a poorly studied Algol-type eclipsing binary V2247 Cyg. The data analysis is based on our numerous precise UBVRcIc…
The light curves of type II-P SN 2017eaw: first 200 days
D. Yu. Tsvetkov, S. Yu. Shugarov, I. M. Volkov +7
We present UBVRI photometry of the supernova 2017eaw in NGC 6946, obtained in the period from May 14 until December 7, 2017. We derive dates and magnitudes of maximum light in the…
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…
Survey of Period Variations of Superhumps in SU UMa-Type Dwarf Novae. VIII: The Eighth Year (2015-2016)
Taichi Kato, Franz-Josef Hambsch, Berto Monard +75
Continuing the project described by Kato et al. (2009, arXiv:0905.1757), we collected times of superhump maxima for 128 SU UMa-type dwarf novae observed mainly during the 2015-2016…
