... The dynamics of silicate and graphite particles with radii of (0.1-2) 10 -5 cm in the vicinity of the Milky Way is considered. The equation of motion of dust grains is integrated with gravitational attraction, radiation pressure, gas drag, and dust destruction taken into account. The effect of other factors on the motion of grains are discussed. ... Dust is swept out of the Galaxy by radiation pressure from stars at a rate of 0.04 M o yr -1 . ...
