Three-dimensional hydrodynamic simulations of L2 Puppis.

CHEN Z., NORDHAUS J., FRANK A., BLACKMAN E.G. and BALICK B.

Abstract (from CDS):

Recent observations of the L_2 Puppis system suggest that this Mira-like variable may be in the early stages of forming a bipolar planetary nebula. As one of nearest and brightest asymptotic giant branch (AGB) stars, thought be a binary, L_2 Puppis serves as a benchmark object for studying the late-stages of stellar evolution. We perform global, three-dimensional, adaptive-mesh-refinement hydrodynamic simulations of the L_2 Puppis system with astrobear. We use the radiative transfer code radmc-\scriptstyle 3d to construct the broad-band spectral energy distribution and synthetic observational images from our simulations. Given the reported binary parameters, we are able to reproduce the current observational data if a short pulse of dense material is released from the AGB star with a velocity sufficient to escape the primary but not the binary. Such a situation could result from a thermal pulse, be induced by a periastron passage of the secondary, or could be launched if the primary ingests a planet.
