摘要：

From radio to X-ray wavelengths, AB Doradus has been an intensively studied star. We have identified similar to30 nearby star systems, each with one or more characteristics of youth, that are moving through space together with AB Dor. This diverse set of similar to50 million year old star systems is the comoving, youthful group closest to Earth. The group's nucleus is a clustering of a dozen stars similar to20 pc from Earth that includes AB Dor itself. The AB Dor moving group joins the previously known and somewhat younger and more distant Tucana/Horologium and TW Hydrae associations and the beta Pictoris moving group as excellent laboratories for investigations of forming planetary systems.
