Exotic states of matter such as free quarks do not arise inside neutron stars, according to a new analysis of one of the super-dense stellar corpses. The result contradicts previous theories and offers an unprecedented view into the behaviour of matter under extreme pressure.

A variety of effects appear to conspire to prevent the formation of quark stars. It casts doubts on the ability to form stellar mass black holes from core collapse events. I suspect SM black holes can only form from inspiraling binary neutron stars. This is a fairly rare event and would nicely explain why so few candidates are apparent.

After reading the article, it seems that the current evidence does not support the existence of exotic matter stars. The study mentioned in the article, which analyzed the behavior of a neutron star, found no evidence of exotic states of matter such as free quarks. This is significant because previous theories had suggested that these exotic states of matter could exist inside neutron stars due to the extreme pressures and densities present.

The fact that this study did not find any evidence of exotic matter supports the current understanding of the behavior of matter at extreme conditions. It also offers new insights into the properties of neutron stars and the behavior of matter under such intense pressures.

However, it is important to note that this study is just one piece of the puzzle and further research and observations are needed to fully understand the nature of neutron stars and the possibility of exotic matter stars. It is possible that there are still unknown factors at play that could lead to the existence of exotic matter stars.

Overall, while the current evidence does not support the existence of exotic matter stars, this is an exciting and ongoing area of research that could potentially lead to new discoveries and a deeper understanding of the universe.
