The Dependence of Stellar Activity Cycles on Effective Temperature
《Research in Astronomy and Astrophysics》2022年第12期198-210,共13页Leonid Kitchatinov 
financially supported by the Ministry of Science and High Education of the Russian Federation。
This paper proposes the idea that the observed dependence of stellar activity cycles on rotation rate can be a manifestation of a stronger dependence on the effective temperature. Observational evidence is recalled an...
