Compared to mass transfer in cataclysmic variables, the nature of accretion in symbiotic binaries in which red giants transfer material to white dwarfs (WDs) has been difficult to uncover. The accretion flows in a symbiotic ...

We study in this work the evolution of the magnetic field in 'redback-black widow' pulsars. Evolutionary calculations of these 'spider' systems suggest that first the accretion operates in the redback stage, and later the ...

This research is concerned with evolution equations and their forward-backward discretizations. Our rst contribution is an estimation for the distance between iterates of sequences generated by forward-backward schemes, ...

The present work is essentially a continuation of [10], [6], [7] dealing withControl problems where the dynamics are driven by ordinary differentialequations (ODE) [9] and evolution inclusions (EI) governed by nonconvexsweeping ...

Context: The standard cooling models of neutron stars predict temperatures T<104 K for ages t>107 yr. However, the likely thermal emission detected from the millisecond pulsar J0437-4715, of spin-down age ts∼7×109 yr, ...
