The shock break-out of GRB 060218/SN 2006aj

GRB060218/SN2006aj PAGE

Welcome !

 

GRB060218 was discovered by the BAT when it came into the BAT field of view during a pre-planned slew. There is no emission at the GRB location up to -3509 s Swift slewed again to the burst position and the XRT and UVOT began observing GRB060218 159 s later. The BAT light curve is shown with green open squares.
The XRT data are shown with black open circles. For each BAT point we converted the observed count rate to flux (15-150 keV band) using the observed spectra. Combined BAT and XRT spectra were fit with cut-off power-law plus a blackbody, absorbed by interstellar matter in our Galaxy [column density of (0.9-1.1)x1021 cm2] and in the host galaxy at redshift z=0.033. The host galaxy column density is NHz=5.0x1021cm2. Errors are at 1 sigma significance. At a redshift z=0.033 (corresponding to a distance of 145 Mpc with H0=70 km s-1 Mpc-1) the isotropic equivalent energy, extrapolated to the 1-10,000 keV rest frame energy band, is Eiso=(6.2±0.3)x1049 erg. The peak energy in the GRB spectrum is at Ep=4.9+0.4-0.3 keV. These values are consistent with the Amati correlation, suggesting that GRB060218 is not an off-axis event. This conclusion is also supported by the lack of achromatic rise behavior of the light curve in the three Swift observation bands. The BAT fluence is dominated by soft X-ray photons and this burst can be classified as an X-ray flash. The BAT flux has been computed based on the XRT+BAT fit and it is underestimated as the black body component starts dominating the XRT flux (approximately from 1600 s).
A V band light curve is shown with red filled circles. Magnitudes have been converted to fluxes using standard UVOT zeropoints and multiplying the specific flux by the filter Full Width at Half Maximum. Gaps in the light curve are due to the automated periodic change of filters during the first observation of the GRB.


Upper panel: the XRT light curve (0.3-10 keV) is shown with open black circles. Count rate-to-flux conversion factors were derived from time-dependent spectral analysis. We also plot with open black squares the contribution to the 0.3-10 keV flux by the blackbody component. Its percentage contribution is increasing with time, becoming dominant at the end of the exponential decay. The X-ray light curve has a long, slow power-law rise followed by an exponential (or steep power-law) decay. At about 10,000 s the light curve breaks to a shallower power-law decay with index -1.2±0.1 characteristic of typical GRB afterglows. This classical afterglow can be naturally accounted for by a shock driven into the wind by a shell with kinetic energy Eshell~1049 erg. The t-1 flux decline is valid at the stage where the shell is being decelerated by the wind with the deceleration phase beginning at tdec<104 s for Mdot> 10-4(vwind/108 cm s-1) Msun yr-1, consistent with the mass-loss rate inferred from the thermal X-ray component.
Lower panel: the UVOT light curve. Filled circles of different colors represent different UVOT filters: red - V (centered at 544 nm); green - B (439 nm), blue - U (345 nm), light blue - UVW1 (251 nm); magenta - UVM1 (217 nm) and yellow - UVW2 (188 nm). Specific fluxes have been multiplied by their FWHM widths (75, 98, 88, 70, 51 and 76 nm, respectively). Data have been rebinned to increase the signal to noise ratio. The UV band light curve peaks at about 30 ks due to the shock break-out from the outer stellar surface and the surrounding dense stellar wind, while the optical band peaks at about 800 ks due to radioactive heating in the SN ejecta.




 

Upper panel: evolution of the temperature of the soft thermal component. The joint BAT and XRT spectrum has been fit with a blackbody component plus a (cut-off) power-law in the first ~3,000 s (see also the caption of first Figure). The last point (circled in green) comes from a fit to the six UVOT filters, assuming a blackbody model with Galactic reddening [E(B-V)=0.14] and host galaxy reddening. This reddening has been determined by fitting the Rayleigh-Jeans tail of the blackbody emission at 32 ks (9 hours). The data require an intrinsic E(B-V)=0.20±0.03 (assuming a Small Magellanic Cloud reddening law).
Lower panel: evolution of the radius of the soft thermal component. The last point (circled in green) comes from the fitting of UVOT data. The continuous line represents a linear fit to the data.
