Tidal evolution of eccentric orbits in massive binary systems
We study the tidal evolution of a binary system consisting of a 1.4M⊙ compact object in elliptic orbit about a 10M⊙ uniformly rotating main sequence (MS) star for various values of the initial orbital parameters. We apply our previously published results of 2D non-adiabatic calculations of the non-radial gand r-mode oscillations of the uniformly rotating MS star, and include the effects of reso...
متن کاملOn the mass transfer process in binary systems
The condition that the radius of one component of a binary star is equal to that of its Roche lobe has so far been used as a criterion for the occurrence of mass transfer. However, this criterion is only approximate. It is introduced for the simplification of the calculations from three-dimensions to onedimension. A modified criterion is introduced, which is more strict and can also be used in ...
متن کاملMass transfer dynamics in double degenerate binary systems
We present a numerical study of the mass transfer dynamics prior to the gravitational wave-driven merger of a double white dwarf system. Recently, there has been some discussion about the dynamics of these last stages, different methods seemed to provide qualitatively different results. While earlier SPH simulations indicated a very quick disruption of the binary on roughly the orbital time sca...
متن کاملThe Evolution of Binary Systems
One of the most important environments in which accretion discs are found occur in interacting binaries. In this chapter I review the main properties of binary systems and the most important types of binary interactions, stable and unstable mass transfer, the role of mass loss, mass accretion and, in the most dramatic case, the merging of the two binary components. I particularly emphasise the ...
متن کاملEccentric Binary Millisecond Pulsars
In this paper we review recent discovery of millisecond pulsars (MSPs) in eccentric binary systems. Timing these MSPs we were able to estimate (and in one case precisely measure) their masses. These results suggest that, as a class, MSPs have a much wider range of masses (1.3 to > 2M⊙) than the normal and mildly recycled pulsars found in double neutron star (DNS) systems (1.25 < Mp < 1.44M⊙). T...
