For cosmic things, many particles that came out of the Big Bang — such as electrons, protons, and neutrons — have been processed in the cores of stars.

Because all elements in the universe heavier than hydrogen, helium, and lithium have been forged by nuclear fusion in the cores of stars and then scattered into space by supernova explosions, the find indicates that the galaxy, at the age we're now observing it, was old enough for at least one generation of stars to have formed, lived, and died.

Carbon, oxygen and nearly all other naturally occurring elements were forged in the cores of stars.

Calculations suggest that under the intense pressure in the cores of these stars, neutrons may pair up to form a frictionless superfluid.

Non-interacting dark matter should sink to the cores of star clusters and dwarf galaxies, but observations show that it is more evenly distributed.

Superbubbles, powered by supernova explosions and young stellar winds, control the way heavy elements, produced only in the cores of stars, are distributed throughout the galaxy, the scientists said.

Because there is a temperature gradient between the core of a star and its surface, energy is steadily transported upward through the intervening layers until it is radiated away at the photosphere.

The core of the star, with 40 percent more mass than our Sun, collapses under its own gravity to a sphere only about 10 miles in diameter, composed mostly of neutrons.
