However, the death of a red dwarf and its subsequent transformation into a white dwarf does not mark the end of its evolutionary journey.
The twinkling orb may look similar to the other fiery stars around it, but it is actually a ideal sphere of crystal.
The crystal spheres are made of carbon and oxygen under such high density their crystal structure will make them appear to be like a metal - although it is possible that diamonds may also form as the star cools. And because white dwarfs are among our cosmos' oldest stellar objects, with predictable life stages, astronomers often use them as "clocks" to date surrounding groups of stars. The core is then formed of a crystallized metallic oxygen interior, with a carbon enhanced mantle.
These excess corresponded to a particular time in the evolution in a star in which they are expected to slow their cooling process and thus age more slowly. Astronomers from the University of Warwick say they've found the first direct evidence that white dwarf stars - the dense, stellar corpses of stars like our sun - can crystallize, or turn from a liquid into a solid.
'The sun itself will become a crystal white dwarf in about 10 billion years'.
'It was predicted fifty years ago that we should observe a pile-up in the number of white dwarfs at certain luminosities and colours due to crystallisation and only now this has been observed. But to find direct evidence, the team turned to data gathered by the European Space Agency's Gaia satellite and analyzed some 15,000 white dwarf candidates.
Dr. Tremblay added that all white dwarfs will eventually crystallize, meaning that "billions of white dwarfs in our galaxy have already completed the process and are essentially crystal spheres in the sky".
According to the authors of the new paper, the release of heat energy alone would not be enough to account for their observations. So understanding this crystallization process could bring greater accuracy when scientists assign ages to the stars.
'All white dwarfs will crystallise at some point in their evolution, although more massive white dwarfs go through the process sooner.
