D. Vokrouhlicky et Wf. Bottke, The Yarkovsky thermal force on small asteroids and their fragments - Choosing the right albedo, ASTRON ASTR, 371(1), 2001, pp. 350-353
Thermal (Yarkovsky) forces acting on small bodies in the solar system have
been shown to play an important role in the the delivery of meteoroids and
km-sized asteroids to Earth. So far, several aspects of the Yarkovsky force
have been studied in some detail, including non-linear effects of the heat
diffusion problem, non-sphericity and the layered-structure of the objects
. In this paper, we address the concept of optical absorptivity. We find th
at the best formulation of the Yarkovsky effect uses the first two moment-i
ntegrals of an object's hemispheric albedo. A useful approximation of these
albedo parameters is an object's Bond albedo.
