Spectral properties of some GRB with presence of high energy component
within RHESSI, HETE and
SWIFT t90 intervals are discussed. In some cases the temporal profiles of GRB
in low and high
energy bands are similar but in some cases they are different and maxima are
not coincide.
We found the same type GRB in CGRO database too – for example, GRB930131.
Moreover, for some GRB
from CGRO and AVS-F database in which spectra contradict Band model high
energy component are present the hard to soft spectral evolution is absent –
for example, for GRB930506 (t90=22.144±0.091) Epeak on burst begin less
than Epeak during other burst parts - Epeak(1-3s)=540±58 keV,
Epeak(3-7s)=1064±38 keV, Epeak(7-23s)=850±32 keV. All GRB with such
properties are long GRB for standatd BATSE and other classifications including
taking in account burst hardness ones.
We suppose that such type GRB consist a new subgroup of long GRB.
