The mechanics of gamma ray bursts

  1. Feb 7, 2016 #1
    I've been googling explanation for gamma ray bursts but couldn't find any that explain how and why the jets actually form, in one website I read that the jets have to be there to "carry off momentum and keep the black hole from spinning too fast", and no other details are mentioned in that regard. How does it keep the black hole from spinning too fast exactly?
    If you can lead me to good articles I would appreciate that

    Thanks your first link was quite useful, it has guided me to good places to look at.
    These are very useful, for anyone interested:

    The leading theory for explaining GRBs is the Blandford–Znajek process

    It says: "In GRBs, a relativistic jet from the collapsing core pushes its way through the stellar envelope."

    All right! Then why shouldn't a collapsing core in a neutron star do the same thing? Thats a good explanation of "how and why the jets actually form".

    Gamma ray ray flashes originate right here on Earth in thunderstorms. Someone should try to explain that as it should be easier than explaining the more distant phenomenon.

    Its interesting that even anti matter can be formed in thunderstorms, but thunderstorms don't help much explaining what happens when a star core collapses.

    It is thought that in NS case, accretion disk either isn't formed at all (say, impeded by magnetic fields, which don't exist in BH case), or if it is formed, it lacks the most energetic inner part (because NS is too big, and accreting material impacts the surface).

    Reviewed theories .... it says: "In GRBs, a relativistic jet from the collapsing core pushes its way through the stellar envelope."

    If a collapsing core makes a GRB burst jet, then a slowly collapsing core in a neutron star should make a continuous jet.
