How about an Electroweak star?

This is presumably one stage higher than a black hole, but two stages
lower than a neutron star, and one stage lower than a quark star. I'm
not sure, it's not mentioned in the article if it's lower or higher than
a quark star.

Also not mentioned in the article is what happens to this star after
about 10 million years, when the electroweak burning phase finishes?
Does it turn into a black hole, or does it turn into a neutron star or
quark star?

And how does a quark turn into a lepton? Is that in the Standard Model?
Or is this coming from an interpretation of one of the Superstring or
some other theories? The only thing I know about the Weak force is how
it causes atomic fission.

SPACE.com -- New Type of Exotic Star Proposed
"An electroweak star could come into being toward the end of a massive
star's life, after nuclear fusion has stopped in its core, but before
the star collapses into a black hole, the researchers found.

At this point, the temperature and density inside a star could be so
high, subatomic particles called quarks (which are the building blocks
of protons and neutrons) could be converted into lighter particles
called leptons, which include electrons and neutrinos.

"In this process, which we call electroweak burning, huge amounts of
energy can be released," the researchers wrote in the scientific paper.

Unfortunately for observers, much of that energy would be in the form of
neutrinos, which are very light neutral particles that can pass through
ordinary matter without interacting, making them very difficult to detect."
