Long-duration Gamma-ray Burst Progenitors and Magnetar Formation

  title={Long-duration Gamma-ray Burst Progenitors and Magnetar Formation},
  author={Cui-Ying Song and Tong Liu},
Millisecond magnetars produced in the center of dying massive stars are one prominent model to power gamma-ray bursts (GRBs). Their detailed nature, however, remains unsolved. To explore the effects of the initial mass, rotation, mass loss, and metallicity of the progenitor stars of 10 − 30 M ⊙ on the formation and properties of the protomagnetars, we evolve over 150 single star models from the pre-main-sequence to core collapse by using the stellar evolution code MESA. We find that all of the…
