But their are problems with PIII stars...
These stars are supposed to be HUGE, being as large as several hundred solar masses. Today no stars can be larger then 110 solar masses. Without enough carbon, oxygen and nitrogen in the core, the CNO cycle could not begin and the star would not produce nuclear fusion properly. Because direct fusion through proton-proton chains does not occur quickly enough to produce the enormous amounts of energy such a star would need to support its immense size and mass. The end result would be the star collapsing into a black hole before the star could even shine properly.
So theoretically they can't exist, but they are needed to explain the emission spectra from quasars. Which is...a big problem.
It's an interesting mystery indeed. But the answers to these problems should be answered by the James Webb Space Telescope when it goes operational, and then the theoretical stars can be observed directly. |
Dragon, the mystery you speak of will not be solved by a telescope,
but by your thoughts and ideas that can encompass more than that.
You have the ability to work out more in your head than any telescope
can tell you, follow that path.
