埃斯基夫:中子星是大质量恒星 ESQUIVE: A neutron star is whats left over 坍缩后剩下的核心 after a massive star collapses in on itself. 密度非常非常大,因为它吸收了 Its very, very dense, because it took all, essentially, 恒星核心的所有质量,并将其收缩成 the mass of the core and contracted ...
It goes like this: the gravitational force between two objects is equal to the mass of one times the mass of the other, multiplied by a very small number called the gravitational constant, and divided by the distan...
motion or spinning and there is not a visible reason for this motion and the invisible reason has an effect that appears to be caused by an object with a mass greater than three solar masses (too big to be a neutron star), then it is possible that a black hole is causing the motion...
Some will get a lot heavier and become strange quarks. Our familiar iron atom will be long gone. We will have squished it into an equal mix of up, down and strange quarks -- in other words, into a strangelet. A strangelet is a small piece of strange matter. Physicists found it ...
Neutron MonitorRandom CoincidenceNeutron MultiplicitySecondary NeutronEvent multiplicities are studied using a unique high-speed detecting system for neutron monitors. It is shown that small and large multiplicities are produced by different physical processes....
Such objects include brown dwarfs, exceedingly dim white dwarfs, neutron stars and even black holes. MACHOs probably contribute somewhat to the dark matter mystery, but there are simply not enough of them to account for all of the dark matter in a single galaxy or cluster of galaxies. ...
supernovae, they blast their elements to space. The best example of a supernova is the Crab Nebula, in Taurus. The core of the original star is left behind as the rest of its material is blasted to space. Eventually, the core could compress to become a neutron star or a black hole....
but no elements of typical interactions were seen. Eventually a theory was developed once astronomers noticed two groupings were present: one every 157 days, the other every 4.6 days. The idea is another star causes the longer-period bursts while a planet close to the neutron star - only abo...
My ten-year-old asked me what this passage means: """ A neutron star is the collapsed core of a massive supergiant star, which had a total mass of between 10 and 25 solar masses, possibly more if the star was especially metal-rich.[1] Neutron stars are the smallest and de...
Gravitational waves from a near neutron star pair could have the effect of displacing the oceans by about 10 times the diameter of an atomic nucleus -- a seemingly small amount, but quite large if we're talking about all the water in the ocean. Although there are only six known pairs of...
