Fallback accretion in the aftermath of a compact binary merger
Recent observations of long and short gamma-ray bursts have revealed a puzzling X-ray activity that in some cases continuous until hours after the burst. It is difficult to reconcile such time scales with the viscous time scales that an accretion disk can plausibly provide. Here I discuss the accretion activity expected from the material that during a compact binary merger coalescence is launch...
متن کاملFingerprint of a Binary Merger
Supernova 1987A, which was the first naked-eye supernova since Kepler’s supernova in 1604. It was an unusual supernova that in many respects defied theoretical expectations. It has long been suspected that these anomalies were the result of the merger of two massive stars some 20,000 years before the explosion, but so far there has been no conclusive proof. Here we present threedimensional hydr...

متن کاملConstraining Population Synthesis Models via Empirical Binary Compact Object Merger and Supernovae Rates
The observed samples of supernovae (SN) and double compact objects (DCOs) provide several critical constraints on population-synthesis models: the parameters of these models must be carefully chosen to reproduce, among other factors, (i) the formation rates of double neutron star (NS-NS) binaries and of white dwarf-neutron star (WD-NS) binaries, estimated from binary samples, and (ii) the type ...
متن کاملA COMPACT BINARY MERGER MODEL FOR THE SHORT, HARD GRB 050509b
The first X–ray afterglow for a short (∼ 30 ms), hard γ–ray burst was detected by Swift on 9 May 2005 (GRB 050509b). No optical or radio counterpart was identified in follow–up observations. The tentative association of the GRB with a nearby giant elliptical galaxy at redshift z = 0.2248 would imply a total energy release Eγ,iso ≈ 3×1048 erg, and that the progenitor had traveled several tens of...
