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 ]
Although it had been thought more than 50 years ago that dust could form in the ejecta of a core-collapse supernova, [58] which in particular could explain the origin of the dust seen in young galaxies, [59] that was the first time that such a condensation was observed. If SN 1987A is a typical representative of its class then the derived mass ...
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]
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.
The current view among astronomers who model Type Ia supernova explosions, however, is that this limit is never actually attained and collapse is never initiated. Instead, the increase in pressure and density due to the increasing weight raises the temperature of the core, [ 3 ] and as the white dwarf approaches about 99% of the limit, [ 12 ] a ...
SN 2023ixf is a type II-L [7] [8] (core collapse) supernova located in the Pinwheel Galaxy. It was first observed on 19 May 2023 by Kōichi Itagaki and immediately classified as a type II supernova. [2] Initial magnitude at discovery was 14.9. [2]
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.
