I've gotten a bit confused about the creation of the neutron star/pulsar, so I was hoping someone could point me in the right direction :) As fusion stops, when reaching the iron phase, the outer layers (hydrogen, helium, carbon... etc.) gets pulled in-wards do to gravity. This creates a bounce effect on the hard surface of the neutron star (Which I suppose is formed from the iron core?), which in turn sends out a shockwave, which then is halted for a bit, and then "re-ignited" due to neutrinos coming from the outer layer of the neutron star - which the creates the supernova explosion. So far so good, or am I missing some details? Now, if I'm not mistaken, neutron stars and pulsars are pretty much the same. They both spin rapidly, but pulsars emit it's two giant light beams due to the strong magnetic fields and synchotron radiation from charged particles in that field (Although I'm not quite sure how, and why, it loses its magnetic field and rotation speed though?). So, what I've read, the fast rotation comes from conservation of angular momentum, and the large magnetic field comes from compressing the original stars magnetic field into a smaller volume, i.e. increasing its strength. But, is the conservation, and magnetic fields, from the full star, with the hydrogen, helium, carbon... layers, or is it only a small collapse in the core that gives rise to these? Hope you understand the questions, and I've made myself clear :) Thanks in advance.
