4Multiple cycles of magnetic activity in the Sun and Sun-like stars and their evolution显示文摘The wavelet transform method for high-quality time-frequency analysis is applied to sets of observations of relative sunspot numbers and stellar chromosphere fluxes of 10 Sun-like stars.Wavelet analysis of solar data shows that in a certain interval of time there are several cycles of activity with periods of duration which vary considerably from each other:from quasi-biennial cycles to 100-yr cycles.Cyclic activity was detected in almost all Sun-like stars that we examined,even those that previously were not considered as stars with cyclic activity according to analysis using a Scargle periodogram.The durations of solar and stellar cycles significantly change during the observation period.Elena Aleksandrovna Bruevich Vasily Vladimirovich Bruevich Boris Pavlovich Artamonov 2018Research in Astronomy and Astrophysics2018,18,7:0
5Long-term trends in solar activity. Variations of solar indices in the last 40 years显示文摘We analyze long-term variations of several solar activity indices(AIs) that have been measured over the last 40 years.With this goal,we study the AIs that characterize the fluxes from different areas in the solar atmosphere.Our consideration of mutual correlations between the solar indices is based on the study of relationships between them in the period from 1950 to 1990.This period of time,covering activity cycles 19–22,is characterized by relatively stable relations between the indices.We investigate the normalized variations of these indices in recent time in relation to their values which were calculated by considering radiation from the Sun in the radio range at a wavelength of 10.7 cm(F10.7) in 1950–1990.The analysis of time series,representing variations of the normalized AI(AIFF) in solar cycles 23–24,shows different trends exist for different indices in terms of their long-term behavior.We assume that variations of normalized International Sunspot Number(SSN),F530.3 and Flare Index,which have shown sharp decreases in the last 40 years,are possibly associated with a decrease in the intensity of large-scale magnetic fields in the photosphere(SSN) and in the corona(the coronal index and the Flare Index).Elena Bruevich Vasily Bruevich 2019Research in Astronomy and Astrophysics2019,19,7:0
6Magnetic cycles of Sun-like stars with different levels of coronal and chromospheric activity——comparison with the Sun显示文摘The atmospheric activity of the Sun and Sun-like stars is analyzed involving observations from the HK-project at the Mount Wilson Observatory, the California and Carnegie Planet Search Program at the Keck and Lick Observatories and the Magellan Planet Search Program at the Las Campanas Observatory.We show that for stars of F, G and K spectral classes, the cyclic activity, similar to the 11-yr solar cycle, is different: it becomes more prominent in K-stars. Comparative study of Sun-like stars with different levels of chromospheric and coronal activity confirms that the Sun belongs to stars with a low level of chromospheric activity and stands apart among these stars by its minimum level of coronal radiation and minimum level of variations in photospheric flux.Elena Shimanovskaya Vasiliy Bruevich Elena Bruevich 2016Research in Astronomy and Astrophysics2016,16,9:0
