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…
Analysis of the interstellar matter at the periphery of the supershell surrounding the CYG OB1 association in 2.12 micron molecular hydrogen line
D. S. Wiebe, T. G. Sitnik, A. S. Rastorguev +7
We present observations of the vdB 130 cluster vicinity in a narrow-band filter centered at a m molecular hydrogen line performed at the Caucasus Mountain Observatory of t…
A revision of the vdB 130 cluster stellar content based on GAIA DR2 Data. Interstellar extinction toward the Cyg OB1 supershell
T. G. Sitnik, A. S. Rastorguev, A. A. Tatarnikova +3
Two star-forming regions are studied: the young embedded open cluster vdB 130 and the protocluster neighbourhood observed in the head and tail of the cometary molecular cloud locat…
Discovery of an unusual bright eclipsing binary with the longest known period: TYC 2505-672-1 / MASTER OT J095310.04+335352.8
V. Lipunov, E. Gorbovskoy, V. Afanasiev +16
We report on the MASTER Global Robotic Net discovery of an eclipsing binary, MASTER OT J095310.04+335352.8, previously known as unremarkable star TYC 2505-672-1, which displays ext…
Star-forming regions at the periphery of the supershell surrounding the Cyg OB1 association. I. The star cluster vdB 130 and its ambient gas and dust medium
T. G. Sitnik, O. V. Egorov, T. A. Lozinskaya +6
Stellar population and the interstellar gas-dust medium in the vicinity of the open star cluster vdB 130 are analysed using optical observations taken with the 6-m telescope of the…
Lithium in the Symbiotic Mira V407 Cyg
A. A. Tatarnikova, P. M. Marrese, U. Munari +4
We report an identification of the lithium resonance doublet LiI 6708A in the spectrum of V407 Cyg, a symbiotic Mira with a pulsation period of about 745 days. The resolution of th…
