J/AZh/88/1217       Solar-like activity of low-mass stars    (Kasova+, 2011)

The evolution of solar-like activity of low-mass stars. Kasova M.M., Livshits M.A. <Astron. Zh. 88, 1217 (2011)> =2011AZh....88.1217K =2011ARep...55.1123K
ADC_Keywords: Stars, G-type ; Stars, atmospheres Abstract: An analysis of data on chromospheric activity obtained in the framework of exoplanet-search programs is presented. Observations of 1334 stars showing that the chromospheric activity of the Sun is clearly higher than for the vast majority of stars in the solar vicinity are used. A comparison of chromospheric and coronal activity led to the identification of a significant group of stars with a low level of chromospheric activity, whose coronal radiation spans wide ranges.
