| Abstract: | We observed the spectrum of 44i Boo in 1981 March and in 1983 March. We found that the equivalent widths of the CaII K and CaI 4227 A lines showed periodic variations with different phases, and that the profile of the Hα line also varied in step. A preliminary analysis is made based on our observations and the recent IUE data and a simple model atmosphere with stellar activity of 44i Boo (B) is proposed. |
