| Abstract: | A study is made of characteristics of the oscillatory process in a sunspot where, in addition to the high brightness in the
cores of the H and K Caii lines, the H∈ line was also in emission. A bright H∈ emission persisted during six days at least.
An analog of the behaviour of the Caii and H∈ lines can be seen, presumably, on dwarf stars dKe and dMe. |
