The diversity of transients from magnetar birth in core collapse supernovae

摘要: Strongly-magnetized, rapidly-rotating neutron stars are contenders for the central engines of both long-duration gamma-ray bursts (LGRBs) and hydrogen-poor super-luminous supernovae (SLSNe-I). Models typical (~minute long) LGRBs invoke magnetars with high dipole magnetic fields (Bd > 1e15 G) short spin-down times, while models SLSNe-I weaker longer times weeks. Here we identify a transition region in space Bd birth period which magnetar can power long GRB luminous SN. In particular, show that 2 ms time ~1e4 s explain observations ultra-long 111209 its associated SN2011kl. For spin down predict even duration (~1e6 s) GRBs brighter supernovae, correlation extends to Swift J2058+05 (commonly interpreted as tidal disruption event). We further previous estimates maximum rotational energy proto-magnetar were too conservative energies up Emax ~1-2e53 erg possible. The model therefore comfortably accommodate extreme requirements recently posed by most supernova ASASSN-15lh. ionization flux from pulsar wind nebula powering ASASSN-15lh may lead an "ionization break-out" X-ray burst over coming months, would be accompanied abrupt change optical spectrum. conclude briefly contrasting millisecond black hole SLSNe GRBs.
