There is a smaller chance that the next core collapse supernova will be produced by a different type of massive star such as a yellow hypergiant, luminous blue variable, or Wolf–Rayet. The chances of the next supernova being a type Ia produced by a white dwarf are calculated to be about a third of those for a core collapse supernova.
A Type II supernova or SNII [1] (plural: supernovae) results from the rapid collapse and violent explosion of a massive star. A star must have at least eight times, but no more than 40 to 50 times, the mass of the Sun ( M ☉ ) to undergo this type of explosion. [ 2 ]
The collapsar model describes a type of supernova that produces a gravitationally collapsed object, or black hole. The word "collapsar", short for "collapsed star", was formerly used to refer to the end product of stellar gravitational collapse, a stellar-mass black hole. The word is now sometimes used to refer to a specific model for the ...
The Type Ib supernova SN 2008D [1] [2] in galaxy NGC 2770, shown in X-ray (left) and visible light (right), at the corresponding positions of the images. (NASA image.) [3]Type Ib and Type Ic supernovae are categories of supernovae that are caused by the stellar core collapse of massive stars.
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] Gravitational collapse is a fundamental mechanism for structure formation in the universe.
Supernova remnants driving a shock through the interstellar medium (ISM). Shocks traveling through a massive star as it explodes in a core collapse supernova. [4] Shocks in interstellar gas, caused by a collision between molecular clouds or by a gravitational collapse of a cloud. Accretion shocks at the edge of galaxy clusters.
Jesse Eisenberg has said goodbye to Hollywood in favor of the Midwest — Indiana, specifically. “I’ve lived in Indiana for a decade on-and-off and that’s where I feel the most comfortable ...
Supernova neutrinos are weakly interactive elementary particles produced during a core-collapse supernova explosion. [1] A massive star collapses at the end of its life, emitting on the order of 10 58 neutrinos and antineutrinos in all lepton flavors. [2] The luminosity of different neutrino and antineutrino species are roughly the same. [3]
