The relationship between lithium and activity in disk population main sequence G and K stars.


Abstract (from CDS):

We present determinations of the lithium abundance (through observations of the LiI 6707.8Å line) in a sample of main sequence stars with spectral types ranging from late F down to M0, selected from the sample of nearby stars which have been observed with the Einstein observatory. We show that lithium abundance is correlated with X-ray luminosity for the cooler stars in our sample (4700>Teff>4000), while no correlation is present for the hotter stars. However, the correlation is almost completely driven by a very small number of high lithium, high X-ray luminosity (and thus plausibly very young) cool dwarfs present in the sample. A number of high lithium K dwarfs are present in the survey, and their characteristics and likely age are discussed in detail.
