The Poynting-Robertson effect is discussed, taking into account the mass loss of meteoroids caused by impact erosion, i.e. by their collision with smaller particles in interplanetary space. This effect, together with the consequent diffraction of light on the particle, can substantially change the radiation-pressure efficiency in the micron and submicron size ranges of particles. A correction function, involving the two phenomena, is derived and applied to the classical Poynting-Robertson equations. It is shown that the impact erosion has very strong effects on the dynamics and lifetimes of microparticles. In comparison with the classical Poynting-Robertson effect, the lifetimes of micrometeoroids are substantially shorter, amounting to only about 10% of the classical Poyting-Robertson lifetimes for initial orbits with eccentricities 0 ≤ e ≤ 0.6. The calculations show that the decay of dust particles in the solar system may result not only from their total destruction or their fall into the sun, but also from their hyperbolic escape in the form of β micrometeoroids.
