[12.10] High Resolution Spectroscopy of Very Active Solar-type Stars

N. R. Drager, J. R. King (University of Nevada, Las Vegas), D. R. Soderblom (Space Telescope Science Institute)

Previous low-resolution spectroscopy has been used to find highly active stars in the vicinity of the Sun for the Northern hemisphere. We have analyzed thirteen such stars, using high-resolution spectroscopy, to look at their ages and confirm their activity levels. Although some of these stars may be close binaries, it is likely that others are single stars or wide binaries. 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.

This work was supported by NSF grant AST-0086576.
