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.
Another possible explanation is that accretion of gas onto the central neutron star can create a disk that drives highly directional jets, propelling matter at a high velocity out of the star, and driving transverse shocks that completely disrupt the star. These jets might play a crucial role in the resulting supernova.
The compression caused by the collapse raises the temperature until thermonuclear fusion occurs at the center of the star, at which point the collapse gradually comes to a halt as the outward thermal pressure balances the gravitational forces. The star then exists in a state of dynamic equilibrium. During the star's evolution a star might ...
In some forms of thermonuclear weapons, the energy from this explosion is then used to implode a capsule of fusion fuel before igniting it, causing a fusion reaction (see Teller–Ulam design). In general, the use of radiation to implode something, as in a hydrogen bomb or in laser driven inertial confinement fusion , is known as radiation ...
Evolutionary stages of the core-collapse supernova: [15] (a) Neutronization phase (b) In-fall of material and neutrino trapping (c) Generation of shock wave and neutrinos burst (d) Stalling of shock wave (e) Neutrino heating (f) Explosion. Near the end of life, a massive star is made up of onion-layered shells of elements with an iron core.
SEATTLE-- A lightning bolt struck a giant tree in Seattle's Washington Park Arboretum Tuesday afternoon and the entire thing exploded. The bark of the tree was literally blow in all directions.
Silicon burning begins when gravitational contraction raises the star's core temperature to 2.7–3.5 billion kelvins . The exact temperature depends on mass. When a star has completed the silicon-burning phase, no further fusion is possible. The star catastrophically collapses and may explode in what is known as a Type II supernova.
It may not be the most appealing feature of a cruise, but ships have strict and discreet procedures to follow if someone dies on board. If you ever hear crew discussing Operation Bright Star, that ...
