Swifts GRB GRB071010B : outlier of the ${\mathrm{E}}_{\mathrm{peak}}^{\mathrm{src}}-{\mathrm{E}}_{\gamma }$ and ${\mathrm{E}}_{\mathrm{iso}}-{\mathrm{E}}_{\mathrm{peak}}^{\mathrm{src}}-{\mathrm{t}}_{\mathrm{jet}}^{\mathrm{src}}$ correlations

Abstract

We present multi-band results for GRB071010B based on \Swift, \Suzaku, and ground-based optical observations. This burst is an ideal target to evaluate the robustness of the ${\mathrm{E}}_{\mathrm{peak}}^{\mathrm{src}}-{\mathrm{E}}_{\mathrm{iso}}$ and ${\mathrm{E}}_{\mathrm{peak}}^{\mathrm{src}}-{\mathrm{E}}_{\gamma }$ relations, whose studies have been in stagnation due to the lack of the combined estimation of ${\mathrm{E}}_{\mathrm{peak}}^{\mathrm{src}}$ and long term optical monitoring. The joint prompt spectral fitting using \Swift/Burst Alert Telescope and \Suzaku/Wide-band All sky Monitor data yielded the spectral peak energy as E${}_{peak}^{src}$ of $86.5_{-6.3}^{+6.4}$ keV and E${}_{iso}$ of $2.25_{-0.16}^{+0.19}\times 10^{52}$ erg with $z=0.947$. The optical afterglow light curve is well fitted by a simple power law with temporal index $\alpha =-0.60\pm 0.02$. The lower limit of temporal break in the optical light curve is 9.8 days. Our multi-wavelength analysis reveals that GRB071010B follows ${\mathrm{E}}_{\mathrm{peak}}^{\mathrm{src}}-{\mathrm{E}}_{\mathrm{iso}}$ but violates the ${\mathrm{E}}_{\mathrm{peak}}^{\mathrm{src}}-{\mathrm{E}}_{\gamma }$ and ${\mathrm{E}}_{\mathrm{iso}}-{\mathrm{E}}_{\mathrm{peak}}^{\mathrm{src}}-{\mathrm{t}}_{\mathrm{jet}}^{\mathrm{src}}$ at more than the 3$\sigma$ level.
