Active Regions on Solar-Type Dwarfs
Abstract
We propose to obtain ultraviolet spectra of late-type dwarfs with known rotation rates to Investigate the emission level of chromospheres and coronae as a function of rotation and age, and to determine the physical structure of active regions or other Inhomogeneities within the atmospheres. The investigation will be carried out jointly and In a coordinated manner with the Mt. Wilson HK photometer program, which will provide continuous monitoring of the program stars before, during, and after the times of IUE observation.
