Electroweak star

An electroweak star is a hypothetical type of
electroweak force. This process occurs in a volume at the star's core approximately the size of an apple, containing about two Earth masses[1] and reaching temperatures on the order of 1015 K.[2]
Formation
The stage of life of a star that produces an electroweak star is theorized to occur after a
gravitational attraction, but may still be withstood by electroweak burning radiation pressure. This phase of a star's life may last upwards of 10 million years.[1]
The energy output of an electroweak star is limited by the quark supply rate, which is dictated by gravitational collapse. Each interaction converts nine quarks into three
GeV per interaction. The energy diffuses out of the star as a mixture of neutrinos and photons. Electroweak stars could be identified through the equal number of neutrinos emitted of all three generations, taking into account neutrino oscillation.[2]
