When the core's mass exceeds the Chandrasekhar limit of about 1.4 M ☉, degeneracy pressure can no longer support it, and catastrophic collapse ensues. [10] The outer part of the core reaches velocities of up to 70 000 km/s (23% of the speed of light) as it collapses toward the center of the star. [11]
During cloud collapse dozens to tens of thousands of stars form more or less simultaneously which is observable in so-called embedded clusters. The end product of a core collapse is an open cluster of stars. [18] ALMA observations of the Orion Nebula complex provide insights into explosions at star birth. [19]
Core collapse can refer to: The collapse of the stellar core of a massive star, such as the core collapse that produces a supernova Core collapse (cluster) , the dynamic process that leads to a concentration of stars at the core of a globular cluster
A central massive object (CMO) is a high mass object or cluster of objects at the centre of a large star system, such as a galaxy or globular cluster.In the case of the former, the CMO may be a supermassive black hole, a nuclear star cluster, or even both together.
The state and type of a stellar remnant depends primarily on the mass of the star that it formed from. The ambiguous term compact object is often used when the exact nature of the star is not known, but evidence suggests that it has a very small radius compared to ordinary stars .
Supernova nucleosynthesis is the nucleosynthesis of chemical elements in supernova explosions.. In sufficiently massive stars, the nucleosynthesis by fusion of lighter elements into heavier ones occurs during sequential hydrostatic burning processes called helium burning, carbon burning, oxygen burning, and silicon burning, in which the byproducts of one nuclear fuel become, after ...

Failed supernovae are thought to create stellar black holes by the collapsing of a red supergiant star in the early stages of a supernova. When the star can no longer support itself, the core collapses completely, forming a stellar-mass black hole, and consuming the nascent supernova without having the massive explosion.
