“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 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 ...
As is the case in AGN jets, the interaction of microquasar jets with the ISM should manifest itself through different observable channels, two of which we explore sequentially in this article: the inflation of radio lobes, and the production of dense shells of swept up ISM around those lobe...
Neutron Stars NASA / Goddard Space Flight Center A neutron star,like a white dwarfor black hole, is actually not a star but a stellar remnant. When a massive star reaches the end of its life it undergoes a supernova explosion. When that occurs, all the outer layers of the star fall in...
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...
It's literally the hottest star in the solar system, but you can't just use a thermometer to figure out how hot it actually is. Instead, scientists use a number of tools and indirect methods to figure this hot math out: Spectroscopy: These instruments split sunlight into its component colo...
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...
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...
