We construct new equations of state for baryons at sub-nuclear densities for
the use in core-collapse supernova simulations. The abundance of various nuclei
is obtained together with thermodynamic quantities. The formulation is an

The detection of neutrinos from massive stellar collapses can teach us a lot
not only about source objects but also about microphysics working deep inside
them. In this study we discuss quantitatively the possibility to extract

The existence of various anomalous stars, such as the first stars in the

Pop III stars are the first stars in the universe. They do not contain metals
and their formation and evolution may be different from that of stars of later
generations. In fact, according to the theory of star formation, Pop III stars
might have ...
