At first thought if the bosonic pion is stable enough in a self organising condensate, then it gives conditions for stability. I guess the problem is the "source" of the pions, and then the conditions to form the condensate.
I haven't studied so much the decay properties of pions. If a cosmic object could expel at large mass of pions, I'm curious what magnitude of time limits the condensate would need to form.
Maybe a super nova could create large enough fraction in mass of pions and collapse fast enough to create the star before the pions could decay.
What do you think?
I didn't understand your comment at all... Let me try to answer anyways. The only way I know a pion condensate could form is in the early universe.
That makes more sense. I didn't consider the abundance of Pions in the early Universe, thanks.
It would be interesting to know how the condensate behaves, if it has super fluid behaviour for example.
You can check the research paper I mention in my article. They have worked on this :)
