PRECISE MEASUREMENT OF STELLAR TEMPERATURES USING LINE-DEPTH RATIOS
The ratio of line depth for two spectral lines is used to determine stellar temperatures with a precision = 10 K = 0.2 percent. For stars between late-F and early-K spectral types, the V I 6251 to Fe I 6253 depth ratio is easy to measure. It is also applicable to other temperature regimes if suitabl...
