"With SN 2018zd, the authors estimate an event rate of 0.6–8.5% of all core collapse supernovae; theoretically, the evolutionary path to their progenitor stars is uncertain." ...

A core-collapse supernova creates only a few tenths of a solar mass worth of metals, Whalen says. Pair-instability supernovae, on the other hand, makes closer to 100 solar masses of metals ...

If the remaining stellar core is between about 1.4 and 3 solar masses, it will collapse into a neutron star, an incredibly dense object composed mostly of neutrons, while if the core is more than ...

For the first time in human history, scientists have watched a core-collapse supernova from beginning to end, in real time. The progenitor star was a red supergiant of about ten solar masses, some ...

What does seem clear, however, is that a core-collapse supernova is now the least likely explanation for the magnetar's formation, making SGR 0501+4516 the best candidate out of the fewer-than-30 ...

Another main supernova type is an iron core-collapse supernova where a massive star -- one more than about 10 times the mass of the sun -- runs out of nuclear fuel and has its iron core collapse ...

Type II or core-collapse supernovae occur when red supergiant stars at least eight times, and up to about 25 times the mass of the Sun, collapse under their own weight and explode.

Asymmetric collapse: Simulations of core-collapse supernovae indicate that existing gravitational-wave detectors such as LIGO could spot telltale signs of cosmic distortions known as gravitational ...
