Observations of Young family asteroids at Maidanak observatory

Abstract

We started observation of members of young asteroid families at Maidanak observatory in Uzbekistan from 2005 June.The young family asteroids may still preserve properties of the original collision of their break-up event because of less orbital/collisional evolutions.A part of colligional properties seems to appear in their lightcurves.The surface spectrum of young family asteroids whose age is known is a good index of time scale of space weathering.Based on above motivations, we started multi bands photometric observations of young family asteroids at Maidanak Observatory, Uzbekistan.We will report here our observations from 2006 January to 2006 May.
