On the origin of the main asteroid belt
The paper discusses the origin of the main asteroid belt closely related to the problem of decreasing the total mass of asteroids by three orders of magnitude in comparison with the initial mass of the protoplanetary disk in this zone. We consider a previously unexplored mechanism for reducing the mass of the asteroid belt connected with sweeping out small dust particles from the asteroid belt. The main dynamic factors are solar radiation and solar wind pressure, the Poynting-Robertson effect and gravitational scattering of dust particles on giant planets, primarily on Jupiter. It is shown that this mechanism of collisional erosion could play a significant role in the formation of the main asteroid belt.
