摘要：
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 T-eff and M/H. Comparison of observed with synthetic colors yields estimates of those parameters generally, but not necessarily under the assumption that log g(cgs) = 5. Results are presented for twelve stars of astrophysical interest.
