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.
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 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.
Under ideal conditions, onlookers can count as many as 100 shooting stars per hour, but hourly rates will not be quite as high this year as a nearly full moon will shine bright on the night of Aug ...
Collapsar type based on initial mass and metallicity. A collapsar is a star which has undergone gravitational collapse. [1] When a star no longer has enough fuel for significant fusion reactions, there are three possible outcomes, depending on the remnant star's mass: If it is less than the Chandrasekhar limit (1.4 solar masses), the star will stabilize and shrink, becoming a white dwarf ...
From Boeing's turbulence and a catastrophic hurricane, to Donald Trump's election victory, "Sunday Morning" host Jane Pauley looks back at key events of a year that was monumental.
The radiant point of the shower is a right angle between the Big Dipper and the bright star Arcturus, according to EarthSky. But the meteors will be visible in all parts of the sky, so it’s not ...
The Nobel Prize-winning event, [6] known as SN 1987A, was the collapse of a blue supergiant star Sanduleak -69° 202, in the Large Magellanic Cloud outside our Galaxy, 51 kpc away. [18] About 10 58 lightweight weakly-interacting neutrinos were produced, carrying away almost all of the energy of the supernova. [ 19 ]
