קולוקוויום בפיזיקה: Planetary Impacts in the Early Solar System

Abstract:

The early Solar System was a violent place. Moon- to Mars-size bodies were colliding and planetary embryos were growing and breaking apart.  There is a growing appreciation of the importance of planetary-scale impacts for sculpting our planetary system.  In this talk I will describe some profound consequences of these collisions on terrestrial planet formation, crustal evolution, moon and moonlets formation, material ejection, and asteroid origins.  A new hypothesis for Earth’s Moon formation will be presented, and the dynamics of moonlets merger explored. The enigmatic composition of the Martian Trojan Asteroids will be linked to their genesis.
