Theme of Diploma Thesis

Orbital evolution of asteroidal fragments due to planet gravitation and thermal effects. Usual reservoir of near Earth objects (dust particles, meteoroids, small asteroids, ...) is the main belt of asteroids. In many works from 70's and 80's there was studied the gravitational mechanism of the transfer of material from the asteroidal belt to Earth, especially the role of resonances with giant planets. We suppose in this work to take into calculations thermal effects acting on asteroidal fragments (objects with size interval 0.1 - 50 m).
