from the newsdesk: Thousands Of Stars Turning Into Crystals
[archaeologynewsnetwork.blogspot.com]

Quote: "The first direct evidence of white dwarf stars solidifying into crystals has been discovered by astronomers at the University of Warwick, and our skies are filled with them"

-comment: this is not direct evidence they only observe atmospheres of white dwarfs, everything that happens internally is built on many assumptions and those assumption fuel their models. They should just report they observed a change (or evolution) in the spectra of the star/planet.

Quote:"white dwarfs, have a core of solid oxygen and carbon due to a phase transition during their lifecycle similar to water turning into ice but at much higher temperatures"

-comment: Again, we do not know what kind of core these objects have, you can not know if you only sample surface phenomena.

Quot:"observations made by the Gaia satellite and analysed data on the stars' luminosities and colours"

-comment: Confirmation they look at the star brightness and colours (spectra)

Quote:"When compared to evolutionary models of stars, the pile-up strongly coincides to the phase in their development in which latent heat is predicted to be released in large amounts, resulting in a slowing down of their cooling process. It is estimated that in some cases these stars have slowed down their aging by as much as 2 billion years, or 15 percent of the age of our galaxy"

-commment: Their evolutionary model for these objects is probably completey wrong, but because the gaia satelite works with such a large sample amount, the observations made can be relativized, a slowing down of a cooling rate (no matter the phase of the astron) is compatible with stellar metamorphosis, hot bright plasmatic stars cool rapidly, the older they get the slower the cooling, thus explaining the great ages of more evolved astrons in stellar metamorphosis.

Quote:"This is the first direct evidence that white dwarfs crystallise, or transition from liquid to solid. 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"

-comment: because the observation may be relative there is a possibility that somehow the data they gathered does hint to a certain evolutionary process in these objects, but going from liquid to solid in Stellar Metamorphosis happens in the waterworld and later stages (where the crust is formed and also diamonds in this crust). But white dwarfs are said to be stars with high temperatures, so what are these objects really?

Quote:"All white dwarfs will crystallise at some point in their evolution, although more massive white dwarfs go through the process sooner. This means that billions of white dwarfs in our galaxy have already completed the process and are essentially crystal spheres in the sky. The Sun itself will become a crystal white dwarf in about 10 billion years"

-comment: crystal spheres and then? This is highly unlikely, what happens after they become crystals? My idea is that they made a mistake in classifying white dwarfs, this is the subject of a future paper on "white dwarfs" in stellar metamorphosis.

Quote:"We've made a large step forward in getting accurate ages for these cooler white dwarfs and therefore old stars of the Milky Way"

-comment: In stellar metamorphosis old stars are planets... food for thought.

Quote:"In addition to the release of latent heat, we find strong evidence that cooling is further slowed by the liberation of gravitational energy from element sedimentation in the crystallizing cores"

-comment: sedimentation in the core...how quaint.

I could not access the paper, too bad, astronomy should have free papers so independent researchers can also review and or criticize the work...

Many questions arise and also ideas wrt Stellar Metamorphosis, i am finishing my classification of Astrons within 20 light years, hopefully soon(ish), then i can work on my white dwarf paper..
