Magnetic Fields in Chemically Peculiar and Related Stars. IX. Main Results Obtained in 2022 and an Analysis of Immediate Prospects Astrophys. Bull. (IF 1.2) Pub Date : 2024-03-02 I. I. Romanyuk
Abstract We review the stellar magnetism studies published in 2022. We analyzed a total of 75 papers, which focus mostly on the study of magnetic fields in chemically peculiar and active cool stars. In the latter, migration of magnetic spots and change of their configuration is observed. Projects of spectrographs and spectropolarimeters for new big telescopes are also presented.

Abstract We have undertaken a search for satellites around edge-on galaxies in the EGIPS catalog, which contains 16 551 objects with declinations above \(-30^{\circ}\) . We searched for systems with a central galaxy dominating in brightness by at least \(1^{\textrm{m}}\) compared to its companions. As a result, we discovered 1097 candidate satellites around 764 EGIPS galaxies with projected distances

Radio Properties of High-Redshift Galaxies at $$\boldsymbol{z\geq 1}$$ Astrophys. Bull. (IF 1.2) Pub Date : 2023-12-01
Abstract Study of high-redshift radio galaxies (HzRGs) can shed light on the active galactic nuclei (AGNs) evolution in massive elliptical galaxies. The vast majority of observed high-redshift AGNs are quasars, and there are very few radio galaxies at redshifts \(z>3\) . We present the radio properties of 173 sources optically identified with radio galaxies at \(z\geq 1\) with flux densities \(S_{1

Abstract A study of the activity of a bright M-dwarf L 98-59, located at a distance of 10.6 pc from Earth is reported. The star has a multiplanetary system, where one of the planets, L 98-59 b, is a rocky planet with a mass not exceeding the mass of Venus. It was found that the level of chromospheric activity of L 98-59 does not exceed the average value characteristic of other cold dwarfs with similar
