In particular, the recent detectionsof short GRBs in galaxies without star formation lends support to the idea that an old stellar population isinvolved. Most prominent are mergers of either double neutron stars or of a neutron star with a stellar-massblack hole companion. Since the final identification of the central engine will only come from an integral viewof several properties, we review the observable signatures that can be expected from both double neutronstars and neutron star black hole systems. We discuss the gravitational wave emission, the structure of theneutrino-cooled accretion disks, the resulting neutrino signal and possible mechanisms to launch a GRB. Inaddition, we address the speculative idea that in some cases a magnetar-like object may be the final outcomeof a double neutron star merger. We also discuss possibilities to explain the late-time X-ray activity that hasbeen observed in several bursts. 2007 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57102708 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Vol.27 |
