The mechanics of gamma ray bursts

In summary: 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.

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

How jets form could be a touchy, argumentative subject; there might be a conflict between neutron star jet observations and the conventional singularity/event-horizon black hole model.

Maybe try: https://en.wikipedia.org/wiki/Astrophysical_jet

And see assumption 9 at: http://www.holoscience.com/wp/strange-star-or-strange-science/

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.

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.
 

Related to The mechanics of gamma ray bursts

1. What are gamma ray bursts (GRBs)?

Gamma ray bursts are the most energetic explosions in the universe, releasing intense bursts of gamma rays, the highest form of electromagnetic radiation. They are thought to be caused by the collapse of massive stars or the collision of neutron stars.

2. How long do gamma ray bursts last?

Most gamma ray bursts last only a few seconds, but some can last up to several minutes. They are classified into two types based on their duration: short and long bursts.

3. What causes the intense radiation in gamma ray bursts?

The intense radiation in gamma ray bursts is caused by a process known as synchrotron radiation, where electrons are accelerated to near the speed of light and emit high-energy photons as they spiral around magnetic field lines.

4. Can gamma ray bursts harm Earth?

Although gamma ray bursts are incredibly powerful, they are typically located billions of light years away from Earth and do not pose a direct threat to us. However, if a nearby GRB were to occur, it could potentially cause damage to the Earth's ozone layer and disrupt our atmosphere.

5. How do scientists study gamma ray bursts?

Scientists use a variety of telescopes and instruments to study gamma ray bursts, including space-based telescopes like NASA's Swift and Fermi missions, as well as ground-based telescopes. They also analyze data from different wavelengths of light to understand the physics behind these explosive events.
