A Star 2.5 Times the Mass of the Sun and Collapsed to a Size of 12 Km Rotates with a Speed of 1.2 Rev. per Second. (Extremely Compact Stars of this Kind Are Known as Neutron Stars. Certain Stellar Objects Called Pulsars Belong to this Category). Will an Object Placed on Its Equator Remain Stuck to Its Surface Due to Gravity - Physics | Shaalaa.com

20K views · 344 reactions | A supernova is the colossal explosion of a star. Scientists have identified several types of supernova. One type, called a “core-collapse” supernova, occurs in the last stage in the life of massive stars that are at least eight times larger than our Sun. As these stars burn the fuel in their cores, they produce heat. | Science Queries 360 | Facebook

SOLVED:Large stars can explode as they finish burning their nuclear fuel, causing a supernova. The explosion blows away the outer layers of the star. According to Newton's third law, the forces that push the outer layers away have reaction forces that are inwardly directed on the core of the star. These forces compress the core and can cause the core to undergo a gravitational collapse. The gravitational forces keep pulling all the matter together tighter and tighter, crushing atoms out of exist
