No, but it DID come from an exploding supernova star! Every atom heavier than lithium has been created in the cores of stars. And if it isn't still in the star, then the star must have exploded to release it.
Thermonuclear fusion is still going on in the core of a red giant, but it is a different type of thermonuclear fusion. The center of the core has reached high enough temperature and pressure that it can now burn helium, producing carbon. 3 4He --> 12C The large amount of energy released by this type of fusion pushes the outer layers away, making a giant star. The expansion of volume of the surface layer causes it to cool, appearing red. Thus a red giant.
A red giant, when a main sequence star begins fusing helium into carbon in the star's core. When our Sun becomes a red giant, in another 4 billion years or so, it will expand to consume Mercury and Venus at least, and possibly the Earth as well.
the molten iron core
Neptune doesn't have an outer core. The only core Neptune has is the molten inner core in the middle of the planet. Neptune is a gas giant, which means it does not have a solid surface.
Yes, if the star is massive enough when the core collapses a supernova explosion happens.
A white dwarf
Most likely a giant core of ice, or somehow a giant core of boiling magma.
No. In a red giant, fusion occurs in a shell around the core.

A giant star is a dying star that expanded, and the core shrinks are the same time. When the shell of the giant star drift into space as planetary nebula, the core became a white dwarf. The white dwarf is made from the core of the giant star.
Nuclear fusion of Hydrogen to Helium is what produces the Sun's Energy. this takes place in the core. Later when it becomes a Red Giant it will fuse Helium to Carbon
No, it is a gas giant.
A red giant forms when a star runs out of hydrogen fuel at its core and starts fusing hydrogen in a shell around the core the core. This causes the star to expand and cool.
Not sure about an 'Osotope' Isotope: A variation in the number of neutrons in the core of an atom of a given element is an isotope of that element. Carbon has six protons in the core of the atom. Carbon-12 has six neutrons in its core. Carbon-13 has seven neutrons. Carbon-13 is an isotope of Carbon.
The earth is magnetic because of the mass of molten iron in its core. Magnetism come from subatomic attraction of particles in some elements including iron and carbon.
Hydrogen fusion to make helium. When a star runs out of hydrogen in its core to fuse, it begins collapsing, leaves the main sequence, then ignites helium fusion to make carbon, becoming a red giant.
I don't think so because diamonds require heat and pressure neither of which is possible to obtain in space. crazy chris says: dude this giant diamond is the core of a white dwarf star the heat of the core left over from the nuclear fusion of the star provided great amounts of heat and the gravitational pull of the sheer mass of the core allowed the pressure to crystalize the core of the star which is mostly carbon into a diamond it is simple physics.
