Title |
Stability of mass transfer in eccentric compact binaries | |||||

Abstract |
Compact binaries are important progenitors for gamma-ray bursts, they constitute the most promising sources of gravitational waves and form an interesting setting for dynamically important nuclear burning processes. Here we present simulations of the onset of mass transfer in compact binaries, focusing on systems containing a neutron star and a white dwarf. These systems are formed interestingly often. A significant fraction of them will come into contact in less than a Hubble time while still being interestingly eccentric. We realistically model the white dwarf by using the Helmholtz equation of state. We make use of a modified form of smoothed particle hydrodynamics, which enables us to model realistically low mass transfer rates for the first time. We use this code to investigate the stability of mass transfer. |
