| To create an X-ray burst, they split away a fraction of the energy of each pulse and use it to intensely heat a copper wire. which detected an X-ray burst in Jupiter's northern midlatitudes minutes after the K impact, may shed light on the auroras. In this model, the energy required to drive the thermonuclear explosion necessary to produce an X-ray burst would come from a special sequence of nuclear fusion reactions in which nuclei capture protons to create new isotopes. |
