843 MHz emission from the active star AB Dor.
Abstract
The Molonglo Observatory synthesis telescope has been used to obtain twelve observations of a 23arcmin arc field containing the active star AB Dor. On each occasion, an unresolved source close to the optical position of AB Dor was observed. The source exhibits day-to-day variations of flux density, with a mean value of ≡4 mJy. The identification of the source with the star and the variations in emission are discussed.
