Evidence for symbiotic nature of 2MASS J21012803+4555377
A. M. Tatarnikov, A. A. Tatarnikova, N. A. Maslennikova +3
Just less than 300 symbiotic stars are currently known in the Galaxy. The population synthesis methods predict that this amount should be 10--100 times larger. In recent years, sev…
Disk in the circumstellar envelope of carbon Mira V Cygni
Boris S. Safonov, Sergey G. Zheltoukhov, Andrey M. Tatarnikov +2
AGB stars are the primary source of dust and complex molecules in the interstellar medium. The determination of outflow parameters is often hindered by the unknown geometry of the…
TESS photometry of the nova eruption in V606 Vul: asymmetric photosphere and multiple ejections?
Kirill V. Sokolovsky, Elias Aydi, Konstantin Malanchev +70
Lightcurves of many classical novae deviate from the canonical "fast rise - smooth decline" pattern and display complex variability behavior. We present the first TESS-space-photom…
Recurrent Symbiotic Nova T Coronae Borealis Before Outburst
N. A. Maslennikova, A. M. Tatarnikov, A. A. Tatarnikova +5
The results of photometric and spectral observations of T CrB obtained in a wide range of wavelengths in 2011-2023 are presented. We use the near-IR light curves to determine a new…
The Post-AGB Star IRAS 07253-2001: Pulsations, Long-Term Brightness Variability and Spectral Peculiarities
N. P. Ikonnikova, M. A. Burlak, A. V. Dodin +5
The observations and comprehensive study of intermediate initial mass stars at the late stages of evolution, and after the asymptotic giant branch (AGB) in particular, are of cruci…
Orbital parameters and activity of ZZ Tau -- a low mass young binary with circumbinary disc
A. Belinski, M. Burlak, A. Dodin +5
We present the results of our new observations of the young binary ZZ Tau with a circumbinary disc. The system was found to consist of two coeval (age Myr) classical T Tauri s…
FG Sge: new multicolor photometry and short-term dust shell clearing in 2019
V. P. Arkhipova, N. P. Ikonnikova, V. I. Shenavrin +6
We present the results of a new stage of the long-term photometric study of FG Sge which is a quickly evolving central star of the planetary nebula Hen 1-5. Our new observations ca…
Near-infrared detection of H flows in the core of Mon R1 association
T. Yu. Magakian, A. M. Tatarnikov, T. A. Movsessian +1
We report the discovery of 4 new H jets in Mon R1 star-forming region on the images obtained with the 2.5-m telescope of the Caucasian Mountain Observatory of SAI MSU through t…
Photometric and spectroscopic analysis of LBV candidate J004341.84+411112.0 in M31
A. Sarkisyan, O. Sholukhova, S. Fabrika +4
We study Luminous Blue Variable (LBV) candidate J004341.84+411112.0 in the Andromeda galaxy. We present optical spectra of the object obtained with the 6-m telescope of SAO RAS. Th…
RW Aur B: a modest UX Ori type companion of the famous primary
A. Dodin, S. Lamzin, P. Petrov +3
The secondary of the famous young binary RW Aur is much less studied than the primary. To compensate this shortcoming, we present here the results of UBVRIJHK photometric, VRI pola…
Analysis of colour and polarimetric variability of RW Aur A in 2010-2018
A. Dodin, K. Grankin, S. Lamzin +6
Results of photometry and polarimetry of a young star RW Aur A observed during unprecedented long and deep (up to mag) dimming events in 2010-11 a…
Chemical composition of metal-poor stars in Coma Berenices ultra-faint dwarf galaxy as a proxy to individual chemical enrichment events
Tatyana Sitnova, Lyudmila Mashonkina, Andrey Tatarnikov +3
We present NLTE abundances and atmospheric parameters for three metal-poor stars ([Fe/H]<-2) in Coma Berenices ultra-faint dwarf galaxy (UFD). The derived results are based on new…
Spectroscopic and photometric observations of Symbiotic Nova PU Vul during 2009-2016
A. A. Tatarnikova, M. A. Burlak, E. A. Kolotilov +5
A new set of low-resolution spectral and UBVJHKL-photometric observations of the symbiotic nova PU Vul is presented. The binary has been still evolving after the symbiotic nova out…
The jet of the young star RW Aur A and related problems
L. N. Berdnikov, M. A. Burlak, O. V. Vozyakova +3
Comparing the images of the jet of the young star RW Aur A, separated by a period of 21.3 years, we found that the outermost jet's knots have emerged yr ago. We argue…
Comparison of the infrared magnitudes of the eclipsing variable star epsilon Aur during the two main luminance lows using observations from 1980 to 2015
I. A. Maslov, O. G. Taranova, A. M. Tatarnikov +1
The data of photometric measurements of the long-period eclipsing variable epsilon Aur in the two main minima 1982 and 2010 in the spectral range of 1--5 microns are presented. Not…
