On accretion in the eclipsing polar BS Tri
A. I. Kolbin, N. V. Borisov, N. A. Serebriakova +4
We analyze spectroscopic and photometric observations of the eclipsing polar BS Tri. The polar's light curve shape variations can be interpreted by changing contributions of the ac…
SRGe2149+6736 -- the new candidate to AM~Her type variables discovered by eROSITA telescope on "Spectrum--Roentgen--Gamma" orbital observatory
I. F. Bikmaev, A. I. Kolbin, V. V. Shimansky +18
We present the results of the optical identification, classification, as well as analysis of photometric and spectral observations of the X-ray transient SRGe2149+6736 detected by…
Activity of Selected Solar Twins
M. M. Katsova, B. A. Nizamov, A. A. Shlyapnikov
We analyze various tracers of magnetic activity for 23 solar twins which are characterized by significant scatter of lithium abundance in their atmospheres. A level of coronal and…
Is the X-ray bright z = 5.5 quasar SRGE J170245.3+130104 a blazar?
Tao An, Ailing Wang, Yuanqi Liu +11
Jets may have contributed to promoting the growth of seed black holes in the early Universe, and thus observations of radio-loud high-redshift quasars are crucial to understanding…
Star Formation in Outer Rings of S0 galaxies. V. UGC 4599 -- an S0 with gas probably accreted from a filament
O. Sil'chenko, A. Moiseev, D. Oparin +2
Though S0 galaxies are usually thought to be `red and dead', they often demonstrate weak star formation organised in ring structures and located in their outer disks. We try to cla…
Magnetic fluxes of solar active regions of different magneto-morphological classes: I. Cyclic variations
Valentina I. Abramenko, Regina A. Suleymanova, Anastasija V. Zhukova
Data for 3046 solar active regions (ARs) observed since May 12, 1996 to December 27, 2021 were utilized to explore how the magnetic fluxes from ARs of different complexity follow t…
