Aims. We present an extension of our investigations on limb-darkening coefficients computed with spherical symmetrical Phoenix models. The models investigated in this paper cover the range 5000 K ≤ Teff ≤ 10 000 K and complete our previous studies of low effective temperatures computed with the same code.
Methods. The limb-darkening coefficients are computed for the transmission curves of the Kepler, CoRoT, and Spitzer space missions and the Strömgren, Johnson-Cousins, Sloan, and 2MASS passbands. These computations were performed by adopting the least-squares method.
Results. We have used six laws to describe the specific intensity distribution: linear, quadratic, square root, logarithmic, exponential, and a general law with four terms. The computations are presented for the solar chemical composition and cover the range 3.0 ≤ log g ≤ 5.5. The adopted microturbulent velocity and the mixing-length parameter are 2.0 km s-1 and 2.0.
