Abstract
The influence of optical scattering and thermal radiation models an the Yarkovsky-O'Keefe-Radzievskii-Paddack (YORP) effect is studied. Lambertian formulation is compared with Hapke scattering and emission laws and Lommel-Seeliger reflection. Although the form of reflectivity function strongly influences mean torques due to scattering or thermal radiation alone, their combined contribution to the rotation period YORP is not much different from the standard Lambertian values. For higher albedo values the differences between the Hapke and Lambert models become significant for the YORP in attitude.
