Are Superluminous Supernovae and Long GRBs the Products of Dynamical Processes in Young Dense Star Clusters

摘要: Superluminous supernovae (SLSNe) occur almost exclusively in small galaxies (Small/Large Magellanic Cloud (SMC/LMC)-like or smaller), and the few SLSNe observed larger star-forming always close to nuclei of their hosts. Another type peculiar highly energetic are broad-line Type Ic SNe (SN Ic-BL) that associated with long-duration gamma-ray bursts (LGRBs). Also these have a strong preference for occurring (SMC/LMC-like smaller) galaxies, LGRBs brightest spots. Studies nearby similar hosts show spots giant H II regions produced by massive dense young star clusters many hundreds O- Wolf-Rayet-type stars. Such also found abundance within hundred parsecs from nucleus like our own. We argue Ic-BL/LGRBs exclusive products two types dynamical interactions clusters. In model high angular momentum collapsing stellar cores required engines an SN Ic-BL results post-main-sequence mergers dynamically cluster binaries equal-mass components. The merger produces critically rotating single helium sufficient produce LGRB; "metal aversion" is natural consequence model. that, on other hand, could be runaway multiple collisions clusters, we present (and quantize) plausible scenarios how different can produced.
