“But neutron stars are different – they are so dense that dark matter particles are much more likely to interact with the star. If dark matter particles do collide with neutrons in the star, they will lose energy and become trapped. Over time, this would lead to an accumulation of ...
How dense is a white dwarf?White Dwarfs:A white dwarf star is all that remains of a star's core after it depletes the fuel used in nuclear fusion. At first, when the star runs out of hydrogen, it expands into a red dwarf while fusing larger elements. When they are gone, a smaller...
Neutron stars, the incredibly dense remnants of massive stars, and pulsars, which emit beams of radiation like cosmic lighthouses. Each type evokes a different image, a different feeling, and each requires a slightly more nuanced description. And it’s not just about t...
Neutron Star Crash Stellar black holes are also created when two neutron stars, which are small, dense stars made of the core of dead stars, crash into each other, like bumper cars in space. The collision sends out a giant burst of radiation called a gamma-ray, as a new stellar black ...
The remains of the core can form a neutron star or a black hole depending upon the mass of the original star. Lots More Information Related HowStuffWorks Articles How Galaxies Work How the Sun Works How the Earth Works How Dark Matter Works How Black Holes Work Kilonovas Are Some of ...
particles collide and start to form clumps. As these clumps accumulate more material, they grow in mass. Thanks to their own gravity, they pull in even more gas and dust from the surrounding star-forming region. Over a million years (give or take), these clumps mature into dense bodies kn...
This kind of star fuses heavier and heavier elements in its core, eventually becoming so massive that it cannot hold itself up against gravity, Borowski said. The result is a huge explosion called a supernova. The star's core lives on as either a neutron star or a black hole, according ...
This density is also the approximate density of neutron stars (which are basically giant atomic nuclei). When a star runs out of fuel and collapses, this is the densest that it can get. If a star has less than about 3 times...

Finally, the design must allow as much of the material as possible to be fissioned before the bomb explodes. This is accomplished by confining the fission reaction within a dense material called a tamper, which is usually made of uranium-238. The tamper gets heated and expanded by the fissio...
