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…
The jet of BP Tau
A. V. Dodin, S. A. Potanin, M. A. Burlak +6
A strong global magnetic field of young low-mass stars and a high accretion rate are the necessary conditions for the formation of collimated outflows (jets) from these objects. Bu…
Optical Identification and Spectroscopic Redshift Measurements of 216 Galaxy Clusters from the SRG/eROSITA All-Sky Survey
I. A. Zaznobin, R. A. Burenin, A. A. Belinski +34
We present the results of the optical identification and spectroscopic redshift measurements of 216 galaxy clusters detected in the SRG/eROSITA all-sky X-ray survey. The spectrosco…
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…
Speckle Interferometry with CMOS Detector
I. A. Strakhov, B. S. Safonov, D. V. Cheryasov
In 2022 we carried out an upgrade of the speckle polarimeter (SPP) -- the facility instrument of the 2.5-m telescope of the Caucasian Observatory of the SAI MSU. During the overhau…
The envelope of the semiregular variable V CVn
Boris Safonov, Sergei Lamzin, Alexandr Dodin +1
V CVn is a semiregular variable star with a V-band amplitude of mag. This star has an unusually high amplitude of polarimetric variability: up to 6 per cent. It also exh…
Differential speckle polarimetry at Cassegrain and Nasmyth foci
Boris Safonov, Pavel Lysenko, Maria Goliguzova +1
Polarimetric interferometry is a method allowing the study of the distribution of polarized flux at diffraction-limited resolution. Its basic observable is the ratio …
