There is clear evidence that long duration Gamma-ray Bursts are associated with broad-line SNe-Ib/c, although some new studies show that GRBs could be produced in tight binary systems which consist of a massive Wolf-Rayet star and a neutron star companion. Present estimates produce a ratio GRB/SNe-Ibc in the range ∼0.4%-3%.STAMPAenArticlehttps://www.aaptr.com/articles/6332016A&AT...29...99DFIS/05 - ASTRONOMIA E ASTROFISICA
