Simulation of the Yarkovsky Effect in the Motion of Asteroids

Keywords: asteroid, orbit, the Yarkovsky effect, nongravitational acceleration, simulation of the Yarkovsky effect.

Abstract

For a number of the NEAs values of transversal component of additional acceleration and corresponding changes of semi-axes were obtained using optical and radar observations. The changes of semi-axes due to the action of the Yarkovsky effect were obtained from physical theory of the effect. Comparison of these values shows that for about 20 % of asteroids under investigation obtained from observations values exceed values based on the theory. The main source of these differences seems to be the errors of observations. Conclusion can be done that similar comparison is useful for discussion of reality of estimations based on observations.
