Abstract
We tried to detecting Post T Tauri stars(PTTSs) by Lindroos objects.Lindroos objects are binary of about a hundred million years age.The primaries are heavy and already reach to main sequence,but more than half of the secondary has about solar mass and they are thought to PTTSs.By using the position of stars in the images of 2MASS and POSS,proper motion of stars near primary were decided.(The precision is 0".5-0".8/20yr.) As a result,we discovered two Lindroos cluster's candidates that they has same proper motion with its primary.
