Uranium and supernovae explosions

  1. Feb 2, 2007 #1
    Do supernova explosions produce lumps of uranium or atoms of uranium?

    It is conjectured that heavy elements are formed in supernovae.

    These sites give background and overviews.

    The nuclear reactions do not produce enough energy to balance the force of gravity.

    Thanks for the links.They collapse quickly don't they!
    If the star didn't have a uniform mass distribution of iron,at the start,
    would it collapse unevenly,and could this lead to an uneven pressure distribution that could cause the iron core to break up into pieces,stopping the usual kind of supernova explosion?
