Context . The source FH Ser experienced a slow classical nova outburst in February 1970 that was the first ever observed at UV, optical, and IR wavelengths. Its remnant is elliptical has multiple knots. A peculiar ring-like filament lies along its minor axis. Aims We investigate here true 3D spatio-kinematical structure of to assess effects early shaping mass kinetic energy. Methods obtained integral field spectroscopic observations made with Very Large Telescope (VLT) VIsible MultiObject...
ABSTRACT We present the first 3D radiation-hydrodynamic simulations of formation planetary nebulae (PNe) emerging from spiral patterns. use guacho code to create structures as a consequence distortions on geometry intrinsically isotropic wind an asymptotic giant branch (AGB) star produced by companion in circular orbit. found that orbital period binary producing pattern has consequences and shaping PN itself. Stellar systems with longer less entwined spirals, PNe rounder inner cavities,...
