Stellar evolution and the 'O-rich AGB sequence'
F. M. Jimenez-Esteban, D. Engels, P. Garcia-Lario
The `O-rich AGB sequence' is a well defined area occupied by oxygen-rich AGB stars (OH/IR) in the IRAS two-colour diagram [12]-[25] vs [25]-[60]. This sequence is interpreted in te…

From ISO to Spitzer: a new view of the AGB-PN transition phase
P. Garcia-Lario, J. V. Perea Calderon
We present a novel classification scheme for stars evolving in the transition phase between the Asymptotic Giant Branch (AGB) to the Planetary Nebula (PN) stage based on the result…

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…
