Spotting in stars with a low level of activity, cloze to solar activity
Data on the variability of the continuum optical emission are used for the first time to estimate the degree of spotting in stars similar to that of the sun. It is sown that the amount of spotting increases gradually from the sun to the highly spotted stars for which Alekseev and Gershberg constructed the zonal model for the distributions of spots. A close relationship is found between spotting and the power of the x-ray emission from the stars with widely varying levels of activity.
