Scientists may have discovered why neutron stars are so bright. It's the stars' strong magnetic field that boosts the production of luminous X-rays.
Why are they so rare? DNS systems are the endpoints of complex and exotic binary stellar evolution. In the standard model, the two stars must survive multiple stages of mass transfer, including common envelope phases, and not one but two supernova explosions. Prior to the second supernova, t...
While we’ve suspected neutron stars to be key to producing these elements in space, that hypothesis now looks a whole lot more convincing. Indeed, the kilonova that formed from the embers of GW170817 could have produced as much gold as the entire mass of the Earth – that ...
We now know that stars are fueled by nuclear fusion. Each time fusion takes place, energy is released as a by-product. This energy, expelled into space, is what we see as starlight. The fusion process begins when two hydrogen nuclei smash together to form a particle called the deuteron ...
Supergiant stars that are old enough to be fusing helium instead of hydrogen. This process releases more energy, causing the star's outer layers to swell. When a supergiant runs out of fuel, it explodes as a Type II supernova.Answer and Explanation: ...
There is no definite evidence that: magnetic field is stronger in the nuclei of interaction at the macro level to another edge manifestations; but through the same logic can explain why the universe has an extra neutron stars, black holes for reasons of strong magnetic field. ...
can escape. Some smaller stars are big enough to go supernova, but too small to becomeblack holes—they'll collapse into super-dense structures calledneutron starsafter exploding as a supernova. But the sun's not big enough for this fate, either: It has only about one-tenth of the mass...
It's possible not enough of their stars explode in supernovas. Some of the biggest, most intense regions of star formation are found in the smallest of galaxies, and scientists believe this is because stars reaching the ends of their lives in the so-called dwarf galaxies are more likely to...
The MeerTRAP project will also be looking for rapidly rotating neutronstars, called pulsars, to better test our theories of gravity. If a pulsar was found orbiting another star or even a black hole, the change in its rotation could tell us more about how gravity works at the extreme end ...
