During last night's … WebA shock front mathematically represents a traveling surface of discontinuity which can be described as a moving boundary condition inside the continuum. Therefore, this problem could be solved with the use of a shock fitting technique that explicitly locates and tracks the motion of the shock front.

WebConsiderin that the shock-breakout material is moving on-axis towards the observe and the relativistic jet off-axis, we compute the light curves durin the relativistic and the lateral expansion phase. As a particular case we successfully describe the X-ray, optical and radio light curve alongside the spectral energy distribution from the ... Webinto the WD. At ≈2×106 gcm−3, the steepening shock begins to race ahead of the burning, as can be seen by the marked decline in intermediate-mass element synthesis. At this depth, …

WebFor GRB 190829A, some of the properties of a shock breakout origin are satisfied. However, the absence of an accompanying thermal component and energy above the shock breakout critical limit precludes a shock breakout origin. In the afterglow, an unusual long-lasting late-time flare of duration ∼10 4 s is observed. WebThe shock breakout time is measured at half of rise for the left and the right spots. We also report the time at which the luminosity in the central region begins to rise. Time zero is taken 300 ps (FWHM of the laser pulse) before the arrival of the maximum of the laser on target front side, in agreement with that used in hydro-simulations.
Web8 Feb 2011 · The shock breakout process begins at tb ≈ Rw / vsh. The rise time for the light curve is tr ≈ δ R / vsh, where δ R is the distance in from Rw across which the diffusion time equals the shock crossing time. We thus have (δ R) 2 κ DR−2w / c = δ R / vsh, leading to tr ≈ ( Rw / vsh ) ( Rw / Rd ).
