In astronomy, the VaughanâPreston gap refers to the absence of F-, G- and K-type stars with intermediate levels of magnetic activity. That is, Vaughan and Preston noted [ when?] two groups of stars with either high or low levels of activity, separated by an apparent gap. [1] There remains no consensus on the cause of the gap. [2]
