Sentence examples for core of a star from inspiring English sources

Compressed and heated to temperatures hotter than those of the core of a star, the hydrogen atoms will fuse into helium, releasing bursts of thermonuclear energy.

The outward force of the light escaping the core of a star, working with thermal pressure, acts to balance the inward gravitational forces on the outer layers of the star.

Nearby are other stars, which, while not quite reaching LBV 1806-20's girth, are still very large; there are also a proto-star and a neutron star, the burned-out core of a star that exploded in a supernova.

In the core of a star like the Sun, strong gravitational pressure forces together hydrogen plasma – an equal mixture of protons and electrons.

The flow of plasma in the core of a star going supernova is known to be unstable to convection (Herant 1995; Burrows et al. 1995; Janka and Müller 1996; Foglizzo et al. 2006) and/or to another large scale instability known as standing accretion shock instability (Blondin et al. 2003; Foglizzo et al. 2007).

For example, a white dwarf is the dead core of a star that is left after the star has shed its outer layers, that is much smaller than a main-sequence star- roughly the star- roughlyarthe

A pulsar consists of a neutron star, the leftover core of a massive star that has blown up in a supernova explosion.

That process of collapse and expansion resembles what happens when the core of a giant star collapses into a black hole or neutron star, triggering a supernova.

The core of a massive star that has died in a supernova explosion, a neutron star consists of neutrons seasoned with a few protons and electrons, and it packs as much mass as one or two suns into a globe less than 20 kilometers across.

Supernovae can be triggered in one of two ways: by the sudden re-ignition of nuclear fusion in a degenerate star; or by the gravitational collapse of the core of a massive star.

The fact there was mostly helium and very little hydrogen in the gas suggests "the slaughtered star had to have been the helium-rich core of a stripped star," Gezari said.
