Luminosity-Entropic scale Index Relation in GRBs

摘要：

The entropic scale index δ is independent of artificial selection effects and reflects the genuine of the variationof a GRB lightcurve. With the current redshift-known GRB sample, we find a tight Liso-δ(1+z) relation and a tentativecorrelation between Ep and δ for typical GRBs. Two low-luminosity GRBs, 980425 and 060218, are significant outliers ofthe Liso-δ(1+z) relation (in 3σ confidence level), likely favoring the idea that they are of a unique GRB population.
