The remains of high-mass stars, neutron stars are best characterized by their immense density. They have a mass of up to 3 solar masses, yet are only a few kilometers in diameter, hence their density.
1 Μαρ 2013 · The first explicit prediction of neutron stars was made by Walter Baade and Fritz Zwicky at Caltech in December 1933, nearly two years after the discovery of the neutron, in trying to explain the enormous energy released in supernova explosions.
Some neutron stars emit beams of electromagnetic radiation that make them detectable as pulsars, and the discovery of pulsars by Jocelyn Bell Burnell and Antony Hewish in 1967 was the first observational suggestion that neutron stars exist.
He defined two processes that he believed to be the sources of energy in stars. The first one, the proton–proton chain reaction, is the dominant energy source in stars with masses up to about the mass of the Sun.
The Discovery of Neutron Stars. In 1967, Jocelyn Bell, a research student at Cambridge University, was studying distant radio sources with a special detector that had been designed and built by her advisor Antony Hewish to find rapid variations in radio signals. The project computers spewed out reams of paper showing where the telescope had ...
Neutron Stars: The History. 1932 Landau suggests the existence of giant nucleus stars. 1932 Chadwick discovers the neutron. 1934 Baade & Zwicky predict the existence of neutron stars (NSs) as the end products of supernovae.
To explore the structure of atoms, go to the PhET Build an Atom website where you can add protons, neutrons, or electrons to a model and the name of the element you have created will appear. You can also see the net charge, the mass number, whether it is stable or unstable, and whether it is an ion or a neutral atom.
