“…A lot of observational support for NS-NS/NS-BH mergers as sources of short GRBs have been obtained (see, e.g., studies of short GRB locations in the host galaxies [204, 751] and references therein). As well, relativistic jets, associated with GRB of any nature may be sources of GW in the ground-based detectors range [50]. …”

We review the formation and evolution of compact binary stars consisting of white dwarfs (WDs), neutron stars (NSs), and black holes (BHs). Mergings of compact-star binaries are expected to be the most important sources for forthcoming gravitational-wave (GW) astronomy. In the first part of the review, we discuss observational manifestations of close binaries with NS and/or BH components and their merger rate, crucial points in the formation and evolution of compact stars in binary systems, including the treatment of the natal kicks, which NSs and BHs acquire during the core collapse of massive stars and the common envelope phase of binary evolution, which are most relevant to the merging rates of NS-NS, NS-BH and BH-BH binaries. The second part of the review is devoted mainly to the formation and evolution of binary WDs and their observational manifestations, including their role as progenitors of cosmologically-important thermonuclear SN Ia. We also consider AM CVn-stars, which are thought to be the best verification binary GW sources for future low-frequency GW space interferometers.

“…Interestingly the hidden jets can also be detectable sources of gravitational radiation. The acceleration of a relativistic jet produces gravitational radiation [34] that peaks at sub Hz frequencies. Gravitational waves from a long GRB jet at 500 Mpc are below the detection limit of advanced LIGO but are detectable by the proposed sub Hz detector DECIGO [35].…”

After several decades of extensive research the mechanism driving core-collapse supernovae (CCSNe) is still unclear. A common mechanism is a neutrino driven outflow, but others have been proposed. Among those, a long-standing idea is that jets play an important role in SN explosions. Gamma-ray bursts (GRBs) that accompany rare and powerful CCSNe, sometimes called "hypernovae", provide a clear evidence for a jet activity. The relativistic GRB jet punches a hole in the stellar envelope and produces the observed gamma-rays far outside the progenitor star. While SNe and jets coexist in long GRBs, the relation between the mechanisms driving the hypernova and the jet is unknown. Also unclear is the relation between the rare hypernovae and the more common CCSNe. Here we present observational evidence that indicates that choked jets are active in CCSNe types that are not associated with GRBs. A choked jet deposits all its energy in a cocoon. The cocoon eventually breaks out from the star releasing energetic material at very high, yet sub-relativistic, velocities. This fast moving material has a unique signature that can be detected in early time SN spectra. We find a clear evidence for this signature in several CC-SNe, all involving progenitors that have lost all, or most, of their hydrogen envelope prior to the explosion. These include CCSNe that don't harbor GRBs or any other relativistic outflows. Our findings suggest a continuum of central engine activities in different types of CCSNe and call for rethinking of the explosion mechanism of regular CCSNe.Massive stars end their lives in supernova (SN) explosions releasing typically ∼ 10 51 ergs (sometimes called FOE or Bethe) in kinetic energy and a fraction of that in a visible light. 1 arXiv:1704.08298v2 [astro-ph.HE] 2 Jun 2017As the star consumes its energy reservoir its core collapses (hence Core Collapse Supernova -CCSNe) and becomes a compact object. A shock wave that propagates outwards ejects the envelope and synthesizes radioactive 56 Ni that powers part of the visible SN light. So far, in addition to the explosions themselves, we have seen the massive stellar progenitors, neutrinos produced by the newborn neutron star, the compact objects left behind (typically a neutron star) and the expanding matter, (the supernova remnant). All these observations confirm the general picture outline by Baade and Zwicky already in the 1930's [1]. However, while the basic picture is well understood, in spite of several decades of research, the mechanism(s) powering the shocks that drive the SNe is not clear. Models suggested (see e.g.[2] and references therein) include neutrino heating, magnetohydrodynamic, thermonuclear, bounce-shock, acoustic and phase transition mechanisms. The neutrino driven explosion, possibly in combination with hydrodynamic non-spherical instabilities and non-radial flows, is the current favorite (at least for most common core collapses, type II SNe), while others (e.g., bounce-shock) seems highly unlikely. In spite of the importance of 3D effects, th...

Twistors appear to provide a satisfactory treatment of angular momentum for gravitationally radiating systems. The approach is manifestly Bondi-Metzner-Sachs (BMS) invariant, and there are no supertranslation ambiguities. The resulting definitions of center of mass and spin are appealing: unphysical contributions from bad cuts are canceled off from the center of mass, and the spin appears formally as a displacement of the center of mass into the complex. For transitions between asymptotically Minkowskian regimes (non-radiative regimes with purely electric Bondi shear), when there is no supertranslation offset (equivalently, radation memory) between the regimes the results are in agreement with those deducible from other approaches. However, when there is an offset, the results are different. The twistor-derived change-of-origin formula is closely parallel to the specialrelativistic one, with an algebraic cross-product between the energy-momentum and a directiondependent translation derived from the supertranslation. (No supermomenta appear.) There is also a "longitudinal" contribution to the emitted angular momentum (one sensitive to the total energymomentum and not just the emitted energy-momentum), and terms which are both linear and cubic in the gravitational radiation (whereas BMS-based definitions give purely quadratic contributions). The first-order terms mean that the supertranslation offsets can contribute to the exchange of angular momentum with gravitational radiation, even in weak-field limits. This is illustrated with a simple almost-special-relativistic model.
