Density streams in the disc winds of Classical T Tauri stars
P. P. Petrov, K. N. Grankin, E. V. Babina +5
Spectral and photometric variability of the Classical T Tauri stars RY Tau and SU Aur from 2013 to 2022 is analyzed. We find that in SU Aur the H-alpha line's flux at radial veloci…
Spectroscopy of the massive interacting binary UU Cassiopeiae
P. Hadrava, M. Cabezas, G. Djurašević +9
Context. The eclipsing close binary UU Cas is an interacting massive double-periodic system with a gainer star partly hidden in an accretion disk. Aims. In order to study the physi…
Modulated accretion in T Tauri star RY Tau -- stable MHD propeller or a planet at 0.2 AU?
P. P. Petrov, M. M. Romanova, K. N. Grankin +3
Planets are thought to form at the early stage of stellar evolution when the mass accretion is still ongoing. RY Tau is a T Tauri type star at the age of a few Myr, with accretion…
Cool spots on the surface of the active giant PZ Mon
Yu. V. Pakhomov, V. I. Shenavrin, N. I. Bondar' +4
Based on the multiband (BVRIJHKL) photometric observations of the active red giant PZ Mon performed for the first time in the winter season of 2017-2018, we have determined the mai…
Dynamics of wind and the dusty environments in the accreting T Tauri stars RY Tau and SU Aur
P. P. Petrov, K. N. Grankin, J. F. Gameiro +10
Classical T Tauri stars with ages of less than 10 Myr possess accretion discs. Magnetohydrodynamic processes at the boundary between the disc and the stellar magnetosphere control…
Study of variable stars associated with maser sources: G025.65+1.05
A. M. Sobolev, A. P. Bisyarina, S. Yu. Gorda +1
We report variation of K-band infrared (IR) emission in the vicinity of the G025.65+1.05 water and methanol maser source. New observational data were obtained with 2.5m telescope o…
Properties of dwarf stars in Cygnus OB2
O. V. Maryeva, S. Yu. Parfenov, M. V. Yushkin +2
We present the results of investigation of five stars, originally classified as dwarfs, belonging to Cyg OB2 association, their stellar and wind properties. Using both TLUSTY and C…
