“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 ...
DENSE MATTERELEMENTARY PARTICLESSTARS: INTERIORSNEUTRONWHITE DWARFSThe strong electric field at the surface of a strange star is discussed, and a self-consistent model is proposed to cal- culate its capability of supporting a "normal" nuclear material crust. We find that the electric field is ...
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...
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...
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...
What would happen if strange matter met a black hole? If strange matter, which is incredibly dense and stable, were to encounter a black hole, theoretical predictions suggest it might be absorbed. The interaction's specifics, such as whether strange matter could alter the black hole's properti...
Here, the mass of 4 million suns exists as a single, infinitely dense point, known as a singularity [source: NASA]. Circle this black hole for a while (without falling in) and you'd experience time at half the Earth rate. In other words, due to time dilation you'd round out a ...
The reduced number of equations in the angular moment method offers a path forward for solving neutrino flavor-transformation problems in compact astrophysical objects, such as a neutron star merger. Testing the Angular-Moment-Based Approach
dense neutron core finally has the courage to resist gravity, not by releasing energy but through an effect called degeneracy pressure. You can only pack so many neutrons into a box; eventually, they won’t squeeze any tighter without overwhelming force, and in the first stages of a supernova...
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 ...
