Rare ultramassive stars that exceed this limit – for example in the R136 star cluster – might be explained by the following proposal: Some of the pairs of massive stars in close orbit in young, unstable multiple-star systems must, on rare occasions, collide and merge when certain unusual circumstances hold that make a collision possible.

Neutron stars are formed by the gravitational collapse of the cores of larger stars. They are the remnant of supernova types Ib , Ic , and II . Neutron stars are expected to have a skin or "atmosphere" of normal matter on the order of a millimeter thick, underneath which they are composed almost entirely of closely packed neutrons called ...
In the Legends works Death Star (2007), Dark Empire II, Jedi Search and Champions of the Force, an experimental Death Star prototype, DS-X (a durasteel frame surrounding a reactor core, superlaser, engines and a control room) was conceived by Grand Moff Wilhuff Tarkin as a test bed for the first Death Star. It was constructed by Bevel Lemelisk ...
The images show the surface of the star R. Doradus, a red giant star 180 light-years away in the Dorado constellation. The star has a diameter about 350 times that of the sun, and it serves as a ...
It would arise when a star "in the transitional range (~8 to 10 solar masses) between white dwarf formation and iron core-collapse supernovae", and with a degenerate O+Ne+Mg core, [139] imploded after its core ran out of nuclear fuel, causing gravity to compress the electrons in the star's core into their atomic nuclei, [140] [141] leading to a ...
Rather, at a critical moment in its atmospheric entry the enormous ram pressure experienced by the leading face of the meteoroid converts the body's immense momentum into a force blowing it apart over a nearly instantaneous span of time. [7] That is, the mass of the meteoroid suddenly ceases to move at orbital speeds when it breaks up.
If anyone can bring tighty-whities back, it's Aubrey Plaza.. The Parks and Recreation alum, 40, graced the cover of V Magazine’s latest issue, stripping down to her briefs for a special holiday ...
The superbubble Henize 70, also known as N70 or DEM301, in the Large Magellanic Cloud [1]. In astronomy a superbubble or supershell is a cavity which is hundreds of light years across and is populated with hot (10 6 K) gas atoms, less dense than the surrounding interstellar medium, blown against that medium and carved out by multiple supernovae and stellar winds.
