Abstract (from CDS):

Spectral energy distributions from recent model atmospheres covering a broad range of temperature and metallicity are used to synthesize colors for low-mass stars. Color-color diagrams can therefore be prepared in which each point corresponds to a particular combination of Teff and M/H. Comparison of observed with synthetic colors yields estimates of those parameters generally, but not necessarily under the assumption that log gcgs=5.
Result. are presented for twelve stars of astrophysical interest.
