The new observant data for three solar type stars with planets: HD 68988, HD 168746 and HD 187123 are obtained on a Cassegrain telescope in the Crimean astrophysical observatory. The theoretical and experimental research of these stars is carried out. The regularity between the periodicity of chromospheric activity changes of each star and the rotation period of a planet round it is found out by results of the treated data.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
