STELLAR ACTIVITY CYCLES: WHY DO WE NEED IN THE LONG-TERM MEASUREMENTS OF THE MAGNETIC FIELD?
Journal Title: Odessa Astronomical Publications - Year 2017, Vol 30, Issue
Abstract
Solution of the two important problems requires a study of long-term behavior of the magnetic field on stars with nondegenerate matter: firstly, to define the role of the magnetic field on different evolutionary stages of stars; secondly, to know the influence of the star’s activity on space weather in the habitable zone. This brief review summarizes the first results of the long-term magnetic field measurements on selected stars.

LUMINOSITY-LINEAR SIZE RELATION FOR GALAXIES AND QUASARS WITH STEEP RADIO SPECTRUM
Our data for sources with steep radio spectrum, detected with radio telescope UTR-2 at the decametre band give evidence on the great luminosities, linear sizes, characteristic ages of these objects. In connection with su...
CHARACTERISTICS OF THE PERIOD CHANGES INMIRA-TYPE VARIABLES
The period changes in a sample of Miraty pe variables were analysedand classified. Characteristics of the long-term cyclicity in the period changes were obtained.
CONNECTION BETWEEN THE CME VELOCITIES AND DECAMETER RADIO BURSTS PARAMETERS FROM URAN-4 OBSERVATIONS
The paper reports the results of the research of connection between the coronal mass ejections (CME) with the IV type continual decameter bursts parameters. As the parameters characterizing the CME velocity, we used the...
ANGULAR STRUCTURE OF FRII RADIO SOURCES 3C169.1 AND 3C263 AT DECAMETER WAVELENGTHS
The radio galaxy 3C169.1 and the quasar 3C263, located at nearly the same distance with red shift z>0.6, have similar morphological and spectral characteristics. The maps of the sources obtained at decimeter and centimet...
NEUTRINO IN GRAVITATIONAL FIELD
The spin-gravity coupling for highly relativistic fermions according to the classical Mathisson-Papapetrou and quantum Dirac equations is considered. It is stressed that the behavior of fermions in the highly relativisti...
