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.
