Default Cosmic Carats

"Astronomers have discovered a diamond star weighing 10 billion trillion trillion carats. The cosmic gem is the crystallized carbon core of a white dwarf star."

I saw that.

And I checked my calendar to see if it was April Fools Day.

It wasn't.

Default Diamond core

Was that 2010, or 2061?

Followup (just so as not to post twice in a row):
I see it's even made the front page at Slashdot now, and that they even did the rendition justice by calling it "a cheesy, unrealistic simulation" as well. Faceted core, indeed!

"...the white dwarf studied...is not only radiant but also harmonious. It rings like a gigantic gong, undergoing constant pulsations..."
Wonder what the frequency is.
Also, would the material's structure be identical to an Earth diamond? Indistinguishable?

2061, in 2010 Jupiter collapsed into Lucifer, in 2061 Prof. Floyd visits Europa (the banned planet) and sees the big mountain of diamond that formed inside Jupiter.

No. A white dwarf is plasma. It is about as related to diamond as the carbon arc in a spot light.

Is this white dwarf supposed to have cooled down so much that its core has crystallised?
according to what I have read, white dwarfs might have lots of carbon, but it is at a temperature of 8-10 thousand degrees, in the form of a degenerate gas;
only when the star has cooled into a 'black dwarf' would the core crystalise (presumably into diamond).
