Threshold Mass of the General-relativistic Instability for Supermassive Star Cores

The dependence of the final fate of supermassive star (SMS) cores on their mass and angular momentum is studied with simple modeling. SMS cores in the hydrogen-burning phase encounter the general-relativistic instability during stellar evolution if the mass is larger than ∼3 × 10 ^4 M _⊙ . Spherical...
