Spectroscopy and photometry of nearby young solar analogs.

GAIDOS E.J., HENRY G.W. and HENRY S.M.

Abstract (from CDS):

We present new photometry and spectroscopy of 34 stars from a catalog of 38 nearby (d<25 pc) G and K dwarfs selected as analogs to the early Sun. We report that the least active star in our sample is also slowly rotating and probably of solar age. Two other stars appear to be evolved objects that have recently acquired angular momentum. A fourth star may be a spectroscopic binary. Many of the other stars belong to previously identified common proper-motion groups. Space motions, lithium abundances, and Ca II emission of these stars suggest ages between 70 and 800 Myr.
