cds-question@unistra.frgamma-ray-astronomygamma-ray-burstsaccretionThe detections of some long gamma-ray bursts (LGRBs) relevant to mergers of neutron star (NS)-NS or black hole (BH)-NS, as well as some short gamma-ray bursts (SGRBs) probably produced by collapsars, muddle the boundary of two categories of gamma-ray bursts (GRBs). In both cases, a plausible candidate of central engine is a BH surrounded by a hyperaccretion disc with strong outflows, launching relativistic jets driven by Blandford-Znajek mechanism. In the framework of compact binary mergers, we test the applicability of the BH hyperaccretion inflow-outflow model on powering observed GRBs. We find that, for a low outflow ratio, ~50 per cent, post-merger hyperaccretion processes could power not only all SGRBs but also most of LGRBs. Some LGRBs might originate from merger events in the BH hyperaccretion scenario, at least on the energy requirement. Moreover, kilonovae might be produced by neutron-rich outflows, and their luminosities and time-scales significantly depend on the outflow strengths. GRBs and their associated kilonovae are competitive with each other on the disc mass and total energy budgets. The stronger the outflow, the more similar the characteristics of kilonovae to supernovae (SNe). This kind of 'nova' might be called 'quasi-SN'.2018MNRAS.477.2173Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/477/2173CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/477/2173https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/477/2173http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/477/2173https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/477/2173https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/477/2173http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/477/2173GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/477/2173/table1 (GRBs data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/477/2173/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/477/2173/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/477/2173/table1?GETtext/xml+votable180.050000true189.07529.02333330.0055555555555555566/210 500 503 646 699 3111 3536 3586 4397 4450 4955 5376 5625 5726 5840 6141 6258 7532 7650 8103 8761 9100 9682 9910 10080 10094 10447 10589 10602 10762 11657 12597 13312 13694 13924 14259 15004 15246 15295 15326 15348 16057 16991 17316 17749 17814 17980 18777 18978 19519 19731 19864-19865 19911 19948 21595 22129 22916 24072 25148 25901 25946 26503 27566 27961-27962 28063 28202 28234 28497 29019 31281 31385 31494 31583 32239 32646 33050 33278 33525 33617 33735 34440 34465 34499 34788 34949 35227 35330 35448 35633 36528 37007 39594 40249 40433 41095 42952 44022 44125 45008 45180 45205 45401 45561 45938 46022 46517 46789 47027 47031 47162 47459 48007 48447 48458 48804 48921 49004https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/477/2173?format=asciiGamma-raydefaultJ/MNRAS/477/2173/table1GRBs dataSimbadNameSimbad column added by the CDSmeta.idcharRefReferences (2)meta.refcharzRedshiftsrc.redshiftfloatrecnoRecord number assigned by the VizieR team.
