Synchrotron Maser from Weakly Magnetized Neutron Stars as the Emission Mechanism of Fast Radio Bursts

摘要

The origin of fast radio bursts (FRBs) is still mysterious. All FRBs to date show extremely high brightness temperatures, requiring a coherent emission mechanism. Using constraints derived from the physics of one of these mechanisms, the synchrotron maser, as well as observations, we show that accretion-induced explosions of neutron stars with surface magnetic fields of B_* d 10~(11) G are favored as FRB progenitors.
