Abstract

We propose “dibaryon stars” on the base of the compressible bag model, in which a hadron bag responds microscopic thermal pressure of the other bags and the volume exclusion effect is considered. In general, a free bosonic point-particle matter has no pressure at zero temperature, but a condensed bosonic “bag” matter is able to have a finite pressure because of both the compressibility and the volume exclusion effects. We will show that the condensed dibaryon matter not only produce a very soft equation of state but can also bring the 1.44M mass star.
