Neutron stars can have a resounding impact around the universe. Scientists recently announced the first detection ofgravitational wavescreated by twoneutron starssmashing into each other. 1:33 Gravitational Waves 101What are gravitational waves and how are they detected? These ripples in space-time, ...
A chiral effective field theory approach is used for the description of neutron-dominated nuclear matter present in the outer core of neutron stars. Possible hybrid stars with quark matter in the inner core are discussed using a three-flavor Nambu--Jona-Lasinio model....
That’s about the same as the gravitational pull between you and the Andromeda Galaxy, which is 2.5 million light years away but about a trillion times as massive as the Sun. But when it comes to escaping gravity...
Although the stars look fixed from our point of view on Earth, they're actually moving very rapidly through space, and without anything to steer them away, there's always the chance they could run into another massive body. It's almost like the universe is a giant pool table without any ...
Stellar mass black holes form when massive stars die. If you have read How Stars Work, then you know that a star is a huge, amazing fusion reactor. Because stars are so massive and made out of gas clouds, their own intense gravity is always trying to collapse them. The fusion reac...
Then there are red dwarfs, much smaller and cooler than our own sun, quietly chugging along for trillions of years. Neutron stars, the incredibly dense remnants of massive stars, and pulsars, which emit beams of radiation like cosmic lighthouses. Each type evokes a d...
Because stars are so massive and made out of gas clouds, their own intense gravity is always trying to collapse them. The fusion reactions happening in the core are like a giant fusion bomb that is trying to explode the star. The balance between the gravitational forces and the explosive ...

At first glance, these dazzling events can resemble a supernova — a massive star that explodes at the end of its life when its fuel is exhausted. To distinguish TDEs from supernovae, astronomers keep an eye out for two things. First, they look for a bright flare at the center of a ...
Why are bare quark masses called current quark masses? Is the quark the smallest particle? Why is the top quark so massive? What is the approximate mass of a neutron in atomic mass units? How many quarks are in an atom? How big is a subatomic particle? How are up and down quarks mad...
