Accretion onto the neutron star in Be/X-ray binaries
We study accretion onto the neutron star in Be/X-ray binaries, using a 3D SPH code and the data imported from a high resolution simulation by Okazaki et al. (2002) for a coplanar system with a short period (Porb = 24.3 d) and moderate eccentricity (e = 0.34). We find that a timedependent accretion disk is formed around the neutron star in Be/X-ray binaries. The disk shrinks after the periastron...
متن کاملRadio pulsar and accretion regimes of rapidly rotating magnetic neutron stars in early-type eccentric binaries
Rapidly rotating magnetic neutron stars in eccentric binary systems containing an early type star provide a unique opportunity to investigate the interplay between radio pulsar, stellar wind and accretion phenomena. We summarise the radio pulsar-dominated and the accretiondominated regimes, discussing how the transition from one regime to another can take place as a result of the varying orbita...
متن کاملHoyle–Lyttleton Accretion onto Accretion Disks
We investigate Hoyle–Lyttleton accretion for the case where the central source is a luminous accretion disk. In classical Hoyle-Lyttleton accretion onto a “spherical” source, accretion takes place in an axially symmetric manner around a so-called accretion axis. In the spherical case the accretion rate Ṁ is given as ṀHL(1− Γ), where ṀHL is the accretion rate of the classical Hoyle–Lyttleton acc...
متن کاملDetecting Eccentric Globular Cluster Binaries with LISA
The energy carried in the gravitational wave signal from an eccentric binary is spread across several harmonics of the orbital frequency. The inclusion of the harmonics in the analysis of the gravitational wave signal increases the signal-to-noise ratio of the detected signal for binaries whose fundamental frequency is below the galactic confusion-limited noise cut-off. This can allow for an im...
متن کاملThe gravitational-wave memory from eccentric binaries
The nonlinear gravitational-wave memory causes a time-varying but nonoscillatory correction to the gravitational-wave polarizations. It arises from gravitational-waves that are sourced by gravitationalwaves. Previous considerations of the nonlinear memory effect have focused on quasicircular binaries. Here I consider the nonlinear memory from Newtonian orbits with arbitrary eccentricity. Expres...
