“…Previously, post-SN spin tilt angles have been studied in the context of retrograde orbits in X-ray binaries and their possible connection to long-term periodicities in these systems (Brandt & Podsiadlowski 1995), for BH-NS binaries with a low-mass BH (3 M ⊙ ) and a Roche-lobe filling NS, in the context of precessing jets and their suggested association with gamma-ray bursts (Portegies-Zwart et al 1999), and for binary BH mergers (Postnov & Prokhorov 1999). Based on the dependence of tilt angles on pre-SN binary parameters and NS kick magnitude our results are in agreement with these studies.…”

Spin-orbit misalignment in coalescing compact binaries affects their gravitational radiation waveforms. When the misalignment angles are large ( ∼ > 30 • ), the detection efficiency of the coalescence events can decrease significantly if the misalignment effects are not modeled. In this paper, we consider the formation of close compact binaries and calculate the expected misalignment angles after the second core collapse event.Depending on the progenitor parameters and the assumptions made about supernova kicks, we find that 30%-80% of binaries containing a black hole and a neutron star that coalesce within 10 10 yr have misalignment angles larger than 30 • and a significant fraction of them could remain undetected. The calculations allow us to place strong constraints on the progenitors of such binaries and the kick magnitudes required for their formation. We also discuss the formation of close binaries with two black holes and the effect of non-isotropic kicks.

“…Peculiarly asymmetric gamma-ray bursts [7], although highly uncommon, might be probably explained by more conventional hypothesis, like precessing fireballs (see, for instance, Ref. [8]). Even in the case of galactic microlensing, highly asymmetric curves can be the effect of microlensing by binary stellar systems [9].…”

In this review I summarise the observational connections between accretion and relativistic outflows -jets -in X-ray binaries. I argue that jets are likely to be a fairly ubiquitous property of X-ray binaries as a whole, an assertion which can be tested by further observations of the Atoll-type X-ray binaries. I discuss broad patterns that are emerging from these observational studies, such as a correlation between 'hard' Xray states and the presence of radio emission, and the related anti-correlation between jet strength and mass-accretion rate as inferred from X-ray studies alone. I briefly discuss possible future directions for research and compare X-ray binary jets to those from Active Galactic Nuclei and Gamma Ray Bursts.
