Query: Three-dimensional hydrodynamical models of wind and outburst-related
  accretion in symbiotic systems   Gravitationally focused wind accretion in binary systems consisting of an
evolved star with a gaseous envelope and a compact accreting companion is a
possible mechanism to explain mass transfer in symbiotic binaries. We study the
mass accretion around the secondary caused by the strong wind from the primary
late-type component using global three-dimensional hydrodynamic numerical
simulations during quiescence and outburst stages. In particular, the
dependence of the mass accretion rate on the mass-loss rate, wind parameters
and phases of wind outburst development is considered. For a typical wind from
an asymptotic giant branch star with a mass-loss rate of 1e-6 Msun/year and
wind speeds of 20-50 km/s, the mass transfer through a focused wind results in
efficient infall on to the secondary. Accretion rates onto the secondary of
5-20 per cent of the mass-loss from the primary are obtained during quiescence
and outburst periods where the wind velocity and mass-loss rates are varied,
about 20-50 per cent larger than in the standard Bondi-Hoyle-Lyttleton
approximation. This mechanism could be an important method for explaining
observed accretion luminosities and periodic modulations in the accretion rates
for a broad range of interacting binary systems.
