There can be "refreshed" shocks if the central engine continues to release fast-moving matter in small amounts even out to late times, these new shocks will catch up with the external shock to produce something like a late-time internal shock. This explanation has been invoked to explain the frequent flares … Zobraziť viac Gamma-ray burst emission mechanisms are theories that explain how the energy from a gamma-ray burst progenitor (regardless of the actual nature of the progenitor) is turned into radiation. These mechanisms are … Zobraziť viac It has been known for many years that ejection of matter at relativistic velocities (velocities very close to the speed of light) is a necessary requirement for producing the emission in a … Zobraziť viac The GRB itself is very rapid, lasting from less than a second up to a few minutes at most. Once it disappears, it leaves behind a counterpart at … Zobraziť viac Gamma-ray burst emission is believed to be released in jets, not spherical shells. Initially the two scenarios are equivalent: the center of the jet is not "aware" of the jet edge, and due to relativistic beaming we only see a small fraction of the jet. However, as the … Zobraziť viac A related constraint is imposed by the relative timescales seen in some bursts between the short-timescale variability and the total length … Zobraziť viac There can be "reverse shocks", which propagate back into the shocked matter once it begins to encounter the interstellar medium. The … Zobraziť viac There may be dust along the line of sight from the GRB to Earth, both in the host galaxy and in the Milky Way. If so, the light will be attenuated and reddened and an afterglow spectrum may look very different from that modeled. At very high … Zobraziť viac Webcaused by a refreshed shock (Hascoet et al. 2012). A kilonova/ macronova with a relatively “long-lived” (∼100 ms) hyper-massive neutron star as its central engine was also studied and the r-band data could be reasonably fitted according to this scenario (Kasen et al. 2015). Some colleagues argued that the

WebOn the other hand, in the refreshed-shock scenario both the forward and reverse shock models provide satisfactory fits of the data under some additional conditions on the distribution of the Lorentz factor in the ejecta and the beaming angle of the relativistic outflow.

OE is the only shock AFAIK that is gas filled vs liquid filled so it's lighter there. For finishes the zinc-platting on OE shocks is super light and super effective compared to the polished finish and paint finishes on other shocks. S simplem5
