Formation of massive primordial stars controlled by the protostellar evolution

Memorie della Societa Astronomica Italiana

We present our recent studies following the formation of massive primordial stars under UV radiative feedback, i.e., photoevaporation of circumstellar disks. We stress that the protostellar evolution controls the strength of the UV feedback and thus determines how massive primordial stars finally appear. We propose that large streaming motion of the gas with respect to the dark matter will open a pathway of forming extremely massive (≳ 10<SUP>4</SUP> M_☉) primordial stars. With very rapid mass accretion provided, the protostellar UV feedback is dramatically weakened as the star inflates to have very low effective temperature (T_eff ≃ 5000 K) and small UV emissivity....
