Gravitational collapse of a massive star, resulting in a Type II supernova. Gravitational collapse is the contraction of an astronomical object due to the influence of its own gravity, which tends to draw matter inward toward the center of gravity. [1]
Simulated collision of two neutron stars. A stellar collision is the coming together of two stars [1] caused by stellar dynamics within a star cluster, or by the orbital decay of a binary star due to stellar mass loss or gravitational radiation, or by other mechanisms not yet well understood.
The most massive to explode would be just below the Chandrasekhar limit at around 1.41 solar masses and would take of the order of 10 1100 years, while the least massive to explode would be about 1.16 solar masses and would take of the order 10 32 000 years, totaling around 1% of all black dwarfs.
The Crab Nebula is a pulsar wind nebula associated with the 1054 supernova.It is located about 6,500 light-years from the Earth. [1]A near-Earth supernova is an explosion resulting from the death of a star that occurs close enough to the Earth (less than roughly 10 to 300 parsecs [33 to 978 light-years] away [2]) to have noticeable effects on Earth's biosphere.
After a supernova explosion of a supergiant star, neutron stars are born from the remnants. A neutron star is composed mostly of neutrons (neutral particles) and contains a small fraction of protons (positively charged particles) and electrons (negatively charged particles), as well as nuclei. In the extreme density of a neutron star, many ...
The James Webb Space Telescope captured photos of one of the earliest supernovas ever seen using infrared technology, and creating a time lapse of the phenomena.
Swallowing up planets might be the reason that some stars appear more reddish than others, according to new research published on the preprint server arXiv.
The angular momentum of a stellar black hole is due to the conservation of angular momentum of the star or objects that produced it. The gravitational collapse of a star is a natural process that can produce a black hole. It is inevitable at the end of the life of a massive star when all stellar energy sources are exhausted.
