The advent of hypothetical pion stars - a new form of compact objects in the universe

in steemstem •  7 years ago 

So just to clarify:
The hypothesis is that there is a theoretical phase transition to a somewhat stable Pion condensate within the Quark-Gluon-Plasma regime, right?
Would you also expect a pion star to form out of a further collapsing neutron star or do you require Big Bang conditions for such an abundance of antimatter (antiquarks)?

To my understanding, we are not dealing with the QGP here.

Again from my understanding, they can be potentially formed from pion gases, and are hence disconnected from neutron stars completely. The best moment for their formation is right after the big bang when the universe is full of pions. There is no relation here to the matter-antimatter asymmetry.
