SOLAR SYSTEM

Detailed explanation-1: -After a core collapse supernova, all that remains is a dense core and hot gas called a nebula. When stars are especially large, the core collapses into a black hole. Otherwise, the core becomes an ultra-dense neutron star.

Detailed explanation-2: -That star can either be completely destroyed, become a black hole, or become a neutron star. The outcome depends on the dying star’s mass and other factors, all of which shape what happens when stars explode in a supernova. Neutron stars are among the densest objects in the cosmos.

Detailed explanation-3: -In a typical Type II supernova, the newly formed neutron core has an initial temperature of about 100 billion kelvins, 104 times the temperature of the Sun’s core. Much of this thermal energy must be shed for a stable neutron star to form, otherwise the neutrons would “boil away".

Detailed explanation-4: -After the supernova the remaining core of the star may collapse further. Some become neutron stars while very massive ones become black holes.

Detailed explanation-5: -This shock wave compresses the material it passes through and is the only place where many elements such as zinc, silver, tin, gold, mercury, lead and uranium are produced.

Detailed explanation-6: -These remnants are also called pulsar wind nebulae or plerions, and they look more like a “blob” than a “ring, ‘’ in contrast to the shell-like remnants. The nebulae are filled with high-energy electrons that are flung out from a pulsar in the middle.
