Variability in Gamma‐Ray Bursts: A Clue
Open accessAbstract
We show that external shocks cannot produce a variable gamma-ray burst, unless the burst is produced by an extremely narrow jet (angular opening of ≲10 -4 ) or if only a small fraction of the shell emits the radiation and the process is very inefficient. Internal shocks can produce the observed complex temporal structure provided that the source itself is variable. In this case, the observed temporal structure reflects the activity of the "inner engine" that drives the bursts. This sets direct constraints on it.

“…in many GRBs is in great contrast with the intuitive expectations in the external shock model, which generally predicts a smooth burst temporal profile, and it has been argued that the radiative efficiency is too low for the model so that a much larger energy budget is required (Sari & Piran 1997).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
