Dynamical effects of thermal emission on asteroids

Abstract

An analytical model for the diurnal YORP and Yarkovsky effect is described, which reproduces the overall results from previous numerical studies. Important shape parameters are identified and general forms of the differential equations are presented. The force cosines for comet orbit solutions are modified in order to include both thermal lag and geometrical effects. © 2007 The Author. Journal compilation © 2007 RAS.
