A 3D illustration of a neutron star in the nebula. (Image credit: Shutterstock) Neutron stars are the remnants of giant stars that died in a fiery explosion known as a supernova. After such an outburst, the cores of these former stars compact into an ultradense object with the mass of...
If neutron stars are the remnants or remaining ,traces of exploding stars, then they are the products or results of violent natural processes. Choice A is incorrect. The neutron stars did not cause the explosions; they were caused by the explosions. Choice C is incorrect. There is nothing eq...
Neutron stars are created when massive stars reach the ends of their lives and are composed of the densest matter in the known universe.
“Though we have known that X-ray binaries – some of which are observed as X-ray pulsars – can evolve over millions of years to become rapidly spinning radio pulsars, we were surprised to find one that seemed to swing so quickly between the two.” Neutron stars are the superdense ...
This may not be a word-for-word transcript. Neutron stars are one of the most extreme and violent things in the universe: giant atomic nuclei, only a few kilometers in diameter, but as massive as st…
Neutron stars are not only mines for clues to dense matter physics but may also be the auspicious sources of half of all nuclei heavier than A = 60 in the universe, including the auric isotopes. Although the cold dense matter above the nuclear saturation density cannot be directly explored ...
Extent of spin-up of hot neutron stars just born, during the subsequent cooling stage due to neutrino diffusion, is studied. As a result of the cooling down to cold normal (pion-condensed) stars, about (20 ~ 25) ((50 ~ 90))% increase of rotation rate is found. A comment on the ...
Mysterious and rapid blasts of radiation that sweep over Earth could be the result of starquakes on "dead stars," or neutron stars. This connection could help scientists better understand earthquakes here on our planet. First discovered in 2007, Fast Radio Bursts (FRBs) are invisible to human...

Neutron starsf(R) gravityA gravity theory is considered with the Einstein-Hilbert Lagrangean R + aR 2 + bR μν R μν , R μν being Ricci's tensor and R the curvature scalar. The parameters a and b are taken of order 1 km 2 . Arguments are given which suggest that the ...
