Linearized limb-darkening coefficients for use in analysis of eclipsing binary light curves

Linear limb-darkening coefficients u required in the analysis of eclipsing binary curves are tabulated for a wide range of effective temperature (50 0000 to 40000),wavelength lambda(0.2μ<=lambda <=2.2μ), and gravities g (2.0<=log g<=5.0). The computation is based on the comprehensive range of model atmospheres of Carbon and Gingerich (1969). The results are compared with the theoretical values of Hosokawa (1957), Kopal (1959) and Grygar et al. (1972), and examined in relation to empirically determined values of μ from analyses of eclipsing binary light curves. An improved agreement between theory and observation for the calculated limb-darkening coefficients of the present work is noted. (Auth.)
