HR diagram of our targets with known APs and parallaxes. We display the young stars selected as PMS-like (red circles) and Pleiades-like (orange squares) sources, along with the lithium-rich sub-giant or giant stars (green symbols) and older (black diamonds) sources. The pre-main-sequence evolutionary tracks of Siess et al. (2000) are shown as solid lines with the labels representing their masses. The dashed lines denote the isochrones at ages of 1, 3, 10, 30, and 300 Myr.
