Multi-color photometric observation of a new-born asteroid, (832) Karin

Abstract

We have begun a lightcurve observing project of a very young asteroid family, the Karin family. Though our entire project is still on the way, a multi-color observation in visible wavelength of the biggest member of the family, (832) Karin, gave us a very interesting color variation on its surface. The asteroid has both an old, mature surface that probably had been a part of a parent body of the Karin family, and a new, fresh surface that the collisional event created.
