Magnetic activity on AB Doradus: temporal evolution of star-spots and differential rotation from 1988 to 1994
Magnetic activity on AB Doradus: temporal evolution of star-spots and differential rotation from 1988 to 1994
Surface brightness maps for the young K0 dwarf AB Doradus are reconstructed from archival data sets for epochs spanning 1988 to 1994. By using the signal-to-noise enhancement technique of Least-Squares Deconvolution, our results show a greatly increased resolution of spot features than obtained in previously published surface brightness reconstructions. These …
