Study of Massive OBA Stars with X-ray Emission
E. A. Nikolaeva, I. F. Bikmaev, E. N. Irtuganov +3
A study of the physical parameters of a sample of 15 OBA-type stars with detected X-ray emission from the Spektr-RG/eROSITA telescope is presented. While X-ray emission from cool s…
Mechanisms for magnetic braking boost and disruption: the role of irradiation-driven winds and convective turnover time spike in cataclysmic variables
Vladislav Dodon, Xiang-Dong Li, Xiao-jie Xu +2
The saturated, boosted, and disrupted magnetic braking (SBD MB) model is an empirical prescription that has recently gained support from close-binary observations. Different boosti…
The stellar activity-rotation-age relationship under the lens of asteroseismology
C. Pezzotti, J. Bétrisey, G. Buldgen +6
In low-mass stars, the connection between magnetic activity, rotation period, and age provides key insights into the functioning of dynamos. Fully understanding the activity-rotati…
Spectral Evolution and Photo-ionization Analysis of Nova Cas 2020 (V1391 Cas)
Gamal M. Hamed, Hasan. H. Esenoglu, Almaz. I. Galeev
We present spectroscopic observations of Nova Cas 2020(V1391 Cas) obtained using the Russian Turkish Telescope during different stages of its 2020 outburst. We followed the spectra…
Catalog of variable stars in the WD 0009+501 and GRW +708247 fields based on photometric survey data on transiting exoplanets
O. Ya. Yakovlev, A. F. Valeev, G. G. Valyavin +15
We present a catalog of 150 variable stars, including 13 stars with exoplanet candidates. 37 stars were identified as variables for the first time. As a result of a 2.5-year photom…
Search for LBVs in the Local Volume galaxies: study of four stars in NGC 4449
Y. Solovyeva, A. Vinokurov, A. Sarkisyan +8
We continue to search for LBV stars in galaxies outside the Local Group. In this work, we have investigated four luminous stars in NGC 4449. Multiple spectral observations carried…
