Can optical afterglows be used to discriminate between Type I and Type II GRBs?

Abstract

The precise localization of short/hard (Type I) gamma-ray bursts (GRBs) in recent years has answered many questions but raised even more. I present some results of a systematic study of the optical afterglows of long/soft (Type II) and short/hard (Type I) GRBs, focusing on the optical luminosity as another puzzle piece in the classification of GRBs.Comment: 7 Pages, 2 figures, to be published in the "2008 Nanjing GRB Conference" conference proceedings, figures have been downsample
