The dependence of the YORP effect on an asteroid shape
In this paper we deal with the problem of analytic calculation of the YORP effect of an asteroid in terms of its shape. The calculations are made for spheroidal asteroids, whose shape slightly differs from a triaxial ellipsoid. We analytically describe a real asteroid as a triaxial ellipsoid perturb...
