Abstract
Recent broadband photometry of the chromospherically active single star AB Doradus shows a pattern of variation of the kind associated with large photospheric ‘spots’. An analysis of some recent (1989–1990) photometric data has been made on this basis. Various possible inclination values were tested, and a value of about 70 deg obtained in a previous study was supported. Problems in the data analysis are discussed, and used in a call for frequent high-quality photometry of the star.
