Often when a star is a member of a pair of close-orbiting binary stars, the tidal attraction of the gasses near the center of mass is sufficient to pull gas from one star onto its partner. This effect is especially prominent when the partner is a white dwarf, neutron star, or black hole. Mass loss in binary systems has particularly interesting ...
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 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.
Researchers have discovered a white dwarf (a dead star), with an oxygen atmosphere surrounding it -- the first of its kind. Astronomers managed to pick up the star from spectral lines: colored ...
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 ...
The star, called AG Carinae, is a few million years old and resides 20,000 light-years away inside our Milky Way galaxy. Hubble captures image of bright-burning star that ‘lives fast and dies ...
The jack-in-the-box effect, [1] also known as a turret toss, is a specific effect of a catastrophic kill on a tank or other turreted armored vehicle in which an ammunition explosion causes the tank's turret to be violently blown off the chassis and into the air.
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 ...
