    So a neutron star acts in a similar fashion to a super massive black hole where the accretion disk is not in a constant "feeding mode" with the surface of the body? The difference being that it's magnetic lines of force that's holding material at bay or perhaps funneling them into tight tendrils instead of the binge / purge cycles SMBHs have?

    Yes, that is a very fair picture. There is that image at the top of the article.... But instead of strands perhaps a more dense shell-bubble of strands?

    Default Re: the edge of a neutron star's accretion disk

    I could picture that. Magnetic lines of force simultaneously pushing matter into a sphere or more likely, an oblate disk, around the star. Matter would funnel into the polar regions much like the Van Allen belt does for ionized particles here on Earth. That would be some aurora LOL.
    But I can't get past the enormous gravity of a neutron star. The magnetic field would have to be insanely strong to reshape the accretion disc in the face of that kind of power. Magnetism is a stronger per-unit force than gravity but it drops off much quicker 1/r^3 vs gravity's 1/r^2... close in to that neutron star the magnetic field lines would be like an order of magnitude higher than the gravitational forces... which is really mind blowing.
