This was centere d on the accretion into compact object inside the framework of the induced gravitational collapse (IGC) scenario\, proposed to explain the origin fo r the long-duration gamma-ray burst (GRBs) associated with supernovae type Ic. \; In this one\, a carbon-oxygen core explodes in a Type Ib/c SN in presence of a close neutron star (NS) companion. The SN \; triggers an hypercritical accretion into the NS and if the accretion rate is enoug h high\, the NS can reach its critical mass\, and collapses to a black hol e (BH)\, emitting a GRB . Otherwise\, the system gives place to a x-ray fl ash (XRF). \; With the aim to identify the separatrix of systems in wh ich a BH is formed and characterize the observational signatures of each p rocess\, it was formulated an analytical model based in the Bondy-Hoyle ac cretion formalism. We also performed 3D-SPH numerical simulations of the S N expansion under the presence of the NS companion and explored a wide ran ge of the initial parameter space. https://astronomia.uc.cl/2jucext1/insti tutoastrofisica/instituto/seminarios/evento/353-accretion-onto-compact-obj ects-in-the-induced-gravitational-collapse-scenario-dr-laura-becerra-puc DTSTART:20190529T171500Z DTEND:20190529T174500Z LOCATION:Seminar Room (Instituto de Astrofísica\, Pontificia Universidad Ca tólica\, Vicuña Mackenna 4860\, Santiago\, Chile) SUMMARY:Accretion onto compact objects in the induced gravitational collaps e scenario (Dr. Laura Becerra\; PUC) URL:https://astronomia.uc.cl/2jucext1/institutoastrofisica/instituto/semina rios/evento/353-accretion-onto-compact-objects-in-the-induced-gravitationa l-collapse-scenario-dr-laura-becerra-puc END:VEVENT END:VCALENDAR
