| Abstract: |
We present a novel method for measuring the masses of evolved
stars from their limb-darkening observations parameterized as
a linear-plus-square-root function with two coefficients.
The coefficients of the law are related to integrated moments
of the intensity and carry information about the extension of
the stellar atmosphere, which is correlated to the ratio of the
stellar radius to mass, R/M. Here, we show why the limb-darkening
law is related to the R/M, and apply this result to limb-darkening
observations of the microlensing event EROS-BLG-2000-5. |
