Simplifying this picture we study the surface vibrations of a nonrotating neutron star in the model of a rigid-like inert core covered by the dynamical liquid-like layer; the effects of gravity are described in the Newtonian limit. The eigenfrequencies of surface pulsations are derived in the ...
Matter falling onto the surface of a neutron star would be accelerated to tremendous speed by the star's gravity. The force of impact would likely destroy the object's component atoms, rendering all its matter identical, in most respects, to the rest of the star.[citation needed] Properties...
Gravity from mountains on rapidly rotating neutron stars produces ripples in space-time known as gravitational waves. The Laser Interferometer Gravitational Wave Observatory (LIGO) searches for such waves. Credit: Charles Horowitz Searching for Space-Time Oscillations The study of theseneutron starmountains...
Neutron stars are the densest objects in the universe; the force of gravity at their surface is 1011 times greater than what we experience at Earth’s surface. The interior of a neutron star is composed of about 95% neutrons, with a small number of protons and electrons mixed in. In ...

When the iron core becomes too massive, its ability to support itself by means of the outward explosive thrust of internal fusion reactions fails to counteract the tremendous pull of its own gravity. Consequently, the core collapses. If the core’s mass is less than about three solar masses,...
Supernovae are tied to neutron stars as they are the explosive events that create them. They are so powerful because the star has lost the fight against gravity, and it ends up exploding! Superluminous supernovae are thought to be so luminous due to a magnetar being the power source of ...

They change sign near the surface and remain positive at the radius of the star, which, like the cases of positive α, indicates a possibly different external solution of f(T) gravity than the Schwarzschild one. No steplike changes can be seen in profiles of the cases of negative α. ...
