Neutron stars are one of the most mysterious wonders in the universe. Their extreme densities hint at new and exotic physics at work within. Gravitational waves could be the key to unlocking their secrets. In particular, a first detection of gravitational waves from rapidly-spinning, deformed ...
Evenstarswith masses between 10 and 20 times that of the sun, reach a limit to the heavy elements they can forge (Green, Jones, 2015, pg 251), usually ending up with a core of almost pure iron. Even this heavy element isn't dense enough to prevent massive cores from further collapse....
When a star dies, it may end its life in one of two ways: as a supernova remnant or as a neutron star. Explore stellar death and rebirth, learn how to define a stellar remnant, and discover how explosions form neutron stars.
The formidable magnetic fields of these entities produce high-powered columns of radiation, which can sweep past the Earth like lighthouse beams, creating what's known as a pulsar. The properties of neutron stars are utterly out of this world — a single teaspoon of neutron-star material would...
should be able to detect gravitational waves from thesupernova explosionsthat mark the death of massive stars and the birth of either ablack holeor aneutron star, albeit only within the limits of the Milky Way. Yet, thus far, they have failed to hear the high-pitched chirping of supernova...
While the cosmic tale of the elements is mostly accurate, a new study finds there are still plenty of mysteries in the details. In this work, the team looked at the various ways every stable element from carbon to uranium can be produced in the galaxy. They derived an ...
Scientists believe the heaviest naturally occurring elements, including uranium, are produced in violent neutron-rich environments such as the merger of two neutron stars or supernovae. Under these conditions, neutrons gain nuclei faster than they can decay. ...

Thanks to her study of black holes and neutron stars(中子星),the 17-year-old at Eastlake High School in Washington,the United States,won the top award at the 2022 Regeneron Science Talent Search.It's one of the oldest and best-known science competitions for US high scho...
835 times more massive than an electron. Atoms always have an equal number of protons and electrons, and the number of protons and neutrons is usually the same as well. Adding a proton to an atom makes a new element, while adding a neutron makes an isotope, or heavier version, of that...
