supernova
The heaviest element that can be produced prior to supernova is Iron (Fe).
A nova is when a white dwarf or neutron star in a binary system collects enough hydrogen from its partner star, into an atmosphere around itself that is compressed enough to initiate fusion.A supernova is when a star dies and collapses into a neutron star or black hole, the collapse is fast enough that to conserve momentum the outer layers of the star are violently blown off in an explosion powerful enough to have the excess energy to produce all the elements past iron well into the transuranics. Supernovas only occur in stars that are very large and very hot to begin with.
Pulsars are rapidly rotating neutron stars that emit beams of electromagnetic energy. Neutron stars form when the core of a massive star collapses and goes supernova leaving behind a neutron star which will begin rotating and releasing energy.
Either a neutron star or a black hole. Note: These are not really stars but stellar remnants.

Supernova
A supernova occurs AFTER a star collapses suddenly. See related question
When a star explodes, it is referred to as a nova. If the star is large enough, it will create a super nova. And if the star is dense enough, it does not explode, but instead collapses on itself and forms a black hole
supernova
pulsar star and if it collapses even more a Black hole.
Supernova
when a star collapses it is called a supernova, i learned about it in science today!
When a large star dies, it becomes a black hole because it is no longer hot enough to support itself against gravity
Yes, if the star is massive enough when the core collapses a supernova explosion happens.
The explosion (a supernova) produces a glowing cloud of gas (called a nebula) that slowly expands and dissipates (eg the crab nebula).
