Debris disks provide a unique tool to probe the violent history of terrestrial planet formation and evolution. It is believed that terrestrial planets form on time scales of 10-30 Myr through collisions of planet embryos. Secondary collisions induced in the remaining planetesimals can continue for a few hundred million years. During this violent phase, a large fraction of the mass in the planetesimals is converted into debris. The unexpected large disk found in the Vega system suggests that the fine debris generated in these violent events can be traced as an outflow disk, consisting small grains ejected by photon pressure. In this program, we propose to search for the clouds of fine debris around 5 nearby debris disks. The outcome of the program will be used to estimate the frequency of major planetesimal collisions.
