Abstract:
We have computed limb-darkening coefficients for five commonly used
near infrared photometric bands, namely R, I, J, H, and K, using the
stellar atmosphere models by Kurucz (1993). Since the behaviour of the
specific intensities is very dependent on the range of effective
temperatures considered, we have adopted three analytical
approximations to the limb darkening: linear, quadratic and square
root. The least-squares method has been adopted for the fit of the
limb-darkening coefficients to the model atmospheres.
