Abstract

Previous low-resolution spectroscopy has been used to find stars with highly active chromospheres within 50 pc of the Sun for the Northern hemisphere. We have analyzed thirteen such stars, using high-resolution spectroscopy, to determine Lithium abundances and metallicities. Although two of these stars may be close binaries, it is likely that eleven are single stars or wide binaries, of which four seem to be Pleiades age and two others appear Hyades age. It is usually expected that young stars are to be found in clusters, such as the Pleiades, in which there are many highly active young stars in close proximity to each other. However, we identify several apparently young single nearby field stars.
