Magnetic fields limit the mass of Population III stars even before the onset of protostellar radiation feedback
Piyush Sharda, Shyam H. Menon, Roman Gerasimov +5
The masses of Population III stars are largely unconstrained since no simulations exist that take all relevant primordial star formation physics into account. We perform the first…

The properties of supermassive stars in galaxy merger driven direct collapse I: models without rotation
Lionel Haemmerlé
The formation of the most massive quasars observed at high redshifts requires extreme accretion rates ( M yr). Inflows of M yr are found…

General-relativistic instability in rapidly accreting supermassive stars in the presence of dark matter
Lionel Haemmerlé
The collapse of supermassive stars (SMSs) via the general-relativistic (GR) instability would provide a natural explanation to the existence of the most extreme quasars. The presen…
