The Mid-IR Emission Structure of IRAS 16594-4656
D. A. Garcia-Hernandez, A. Manchado, P. Garcia-Lario +3
We report TIMMI2 diffraction-limited mid-IR images of the multipolar PPN IRAS 16594-4656. By using the Lucy-Richardson deconvolution algorithm we recover a two-peaked morphology in…

The formation of asymmetries in Multiple Shell Planetary Nebulae due to interaction with the ISM
E. Villaver, A. Manchado, G. Garcia-Segura
Multiple shell planetary nebulae (MSPNe) are most likely a consequence of the modulation of the mass-loss rate during the thermal pulses on the AGB. By using numerical simulations…
