| 内容記述 | GRB041006 was first detected by HETE-2 on 2004 Oct. 6 at 12:18:08 UT. We have observed it's earliest optical afterglow from 12:19:18 UT to through the night. Our observation was performed by using the unfiltered CCD camera on the 30-cm telescope. We combined our converted R band data with those reported by GCN. Statistics don't allow us to say in detail but the light curve shows two slope changes. The power-low index α of the flux decay is α =0.62 before about 0.0053 day after the burst, α =-0.45 from 0.0053 day to 0.077 day after the burst, and α =-1 after 0.077 day. These index changes can be explained by forward shock in synchrotron shock model. During the first flat period, optical emission is generated by cooling of all electrons, which are accelerated by forward shock. But the speed of the shell become slower, then the critical frequency becomes lower than the optical band. The light curve, therefore, got dark slowly. And finally, since the minimum frequency at which the slowest ones among the accelerated electrons emit is below the optical frequency, the electrons that can emit optical light decrease rapidly. So the afterglow darkened fast. |
