Photometric activity of CQ Tau on the time interval of 125 years
V. P. Grinin, L. V. Tambovtseva, O. Yu. Barsunova +1
The star CQ Tau belongs to the family of UX Ori type stars. It has very complex photometric behavior and complex structure of the circumstellar environment. In our paper we constru…
The optical behaviour of BL Lacertae at its maximum brightness levels: a blend of geometry and energetics
C. M. Raiteri, M. Villata, S. G. Jorstad +13
In 2021 BL Lacertae underwent an extraordinary activity phase, which was intensively followed by the Whole Earth Blazar Telescope (WEBT) Collaboration. We present the WEBT optical…
Jet from the enigmatic high-latitude star BP Psc and evolutionary status of its driving source
I. S. Potravnov, M. Yu. Khovritchev, S. A. Artemenko +1
BP Psc is an active late-type (sp:G9) star with unclear evolutionary status lying at high galactic latitude . It is also the source of the well collimated bipolar je…
The complex variability of blazars: Time-scales and periodicity analysis in S4 0954+65
C. M. Raiteri, M. Villata, V. M. Larionov +3
Among active galactic nuclei, blazars show extreme variability properties. We here investigate the case of the BL Lac object S4 0954+65 with data acquired in 2019-2020 by the Trans…
Anomalous eclipses of the young star RW Aur A
S. Lamzin, D. Cheryasov, G. Chuntonov +9
Results of UBVRIJHKLM photometry, VRI polarimetry and optical spectroscopy of a young star RW Aur A obtained during 2010-11 and 2014-16 dimming events are presented. During the sec…
Accretion and outflow activity on the late phases of pre-main-sequence evolution. The case of RZ Piscium
I. S. Potravnov, D. E. Mkrtichian, V. P. Grinin +2
RZ Psc is an isolated high-latitude post-T Tauri star that demonstrates a UX Ori-type photometric activity. The star shows very weak spectroscopic signatures of accretion, but at t…
