Gravitational potential energy
... Notation: =0 means solar abundance. [ ] denotes logarithmic ratio. At very early times, [Fe/H]=negative (e.g. =-1.5) since the heavy elements have not be created yet, Type II Supernovae occur at earlier times. They produce both O and Fe and so [O/Fe] is zero. At later times, Type I Supernovae make m ...
