Abstract (English):
The calculations of the motion of planetesimals at the late stages of accumulation of planets in the TRAPPIST-1 system were made. In each calculation variant, initial orbits of planetesimals were near one of the planets. The number of collisions of planetesimals with the planets were calculated. The calculations has shown that the outer layers of neighboring exoplanets in the TRAPPIST-1 system can include similar material if there were a lot of planetesimals near their orbits at the late stages of the accumulation of the exoplanets.
