What is formed in a supernova?

Answer 1

Depending on the mass of the original star, a supernova explosion may cause a neutron star (for medium to large stars) or a black hole (for large or very large stars). If the original star was rotating fairly rapidly, the neutron star may be a "pulsar", the name given to a rapidly spinning neutron star that emits pulses of X-rays. "Rapidly" spinning in this case is upwards of three revolutions per second.

Answer 2

For larger stars, depending on the chemical composition and temperature, the star explodes as a supernova. and either collapses into a neutron star or, if the remaining mass is large enough, the pressure will be insufficient to stop the total collapse and the star will become a black hole.

Answer 4

Supernovas are extremely violent events, and provide enough energy in the presence of smaller nuclei to form nuclei that are even larger than the most stable nucleus, 62Ni (NOT 56Fe, as is often stated).

During a supernova, every element larger than hydrogen will be formed. In the case of the lighter nuclei, stars are continuously forming these elements anyway, so it is impossible to tell whether a particular nucleus was formed in the star before it became a supernova, or whether it was formed in the supernova.

More importantly, in contrast to most stars, nuclei that are heavier than 62Ni may also be formed. Normally, these elements, if formed in stars, are broken down to smaller nuclei, but in a supernova, they may be formed and effectively dispersed before they are broken down.

So, in short, all of the elements up through uranium are formed in a supernova but, almost uniquely, elements heavier than 62Ni are also formed.

Answer 5

By the explosion of a star.

Answer 6

All the heavier elements - actually, all elements found in nature, except for hydrogen.

Answer 7

gold, carbon, and helium
