Merging neutron stars: asymmetric systems
We present the results of 3D, Newtonian hydrodynamic calculations of the last stages of the inspiral and the final coalescence of neutron star binary systems. Our focus is on slightly asymmetric systems, where the asymmetry stems from either different masses (1.3 and 1.4 M⊙) or spins of both components. Almost immediately after contact a fast rotating, very massive central object forms. All cal...
متن کاملBigger Bursts From Merging Neutron Stars
GRB 990123 may have radiated more than one solar mass equivalent in just its gamma emissions. Though this may be within the upper limit of the binding energies available from neutron stars in the Schwarzschild metric, it is difficult to imagine a process with the required efficiency of conversion to gamma rays. Neutron stars of ∼ 10M⊙ are permitted in the Yilmaz metric. A merger of two neutron ...
متن کاملMask Connectivity by Viscous Closings: Linking Merging Galaxies without Merging Double Stars
Second-generation connectivity opened the path to the use of mask images to freely define connectivity among the image components. In theory, any image could be treated as a mask image that defines a certain connectivity. This creates a new problem in terms of which image to use. In this chapter, clustering masks suitable for the analysis of astronomical images are discussed. The connectivity d...
متن کاملHigh Resolution Calculations of Merging Neutron Stars II: Neutrino Emission
The remnant resulting from the merger of two neutron stars produces neutrinos in copious amounts. In this paper we present the neutrino emission results obtained via Newtonian, high-resolution simulations of the coalescence event. These simulations use three-dimensional smoothed particle hydrodynamics together with a nuclear, temperature dependent equation of state and a multi-flavour neutrino ...
متن کاملRadio and X-ray Signatures of Merging Neutron Stars
We describe the possible electromagnetic signals expected from the magnetospheric interactions of a neutron star binary prior to merger. We find that both radio and X-ray signals of detectable strength are possible. We discuss possible links with the phenomenon of gamma-ray bursts and describe the prospects for direct detection of these signals in searches for radio and X-ray transients.
