Abstract

We present what we believe to be the first conclusive evidence for rotational modulation of stellar radio emission, observed on the young and rapidly rotating K1 dwarf star AB Doradus (HD 36705). The radio emission of this star peaked near two stellar longitudes where large starspots have been observed to form preferentially. One of the peaks in radio emission was coincident with the central meridian passage of a large starspot; the starspot associated with the other peak may have been overwhelmed by the visible starspot
