Session 103 - Cool Stars.
Display session, Thursday, January 18
North Banquet Hall, Convention Center
Low-resolution IUE observations of the 280 nm Mg II h and k lines of 67 G--K type stars are used to formulate a relationship between Mg II and Ca II chromospheric emission. The resulting relationship can be used to convert Mg II flux measurements to Ca II flux measurements. This expands the database currently being compiled by the HK Project at Mount Wilson Observatory by providing measurements of chromospheric activity for stars not observable from Mount Wilson. This data will be of use to projects currently using Ca II H and K fluxed from the HK Project.
