Far- and mid-infrared spectroscopy of complex organic matter of astrochemical interest: coal, heavy petroleum fractions, and asphaltenes
F. Cataldo, D. A. Garcia-Hernandez, A. Manchado
The coexistence of a large variety of molecular species (i.e., aromatic, cycloaliphatic and aliphatic) in several astrophysical environments suggests that unidentified IR emission…
Infrared Study of Fullerene Planetary Nebulae
D. A. Garcia-Hernandez, E. Villaver, P. Garcia-Lario +5
We present a study of 16 PNe where fullerenes have been detected in their Spitzer spectra. This large sample of objects offers an unique opportunity to test conditions of fullerene…
A review on carbon-rich molecules in space
F. Cataldo, D. A. Garcia-Hernandez, A. Manchado
We present and discuss carbon-rich compounds of astrochemical interest such as polyynes, acetylenic carbon chains and the related derivative known as monocyanopolyynes and dicyanop…
The nature of dust in compact Galactic planetary nebulae from Spitzer spectra
L. Stanghellini, D. A. Garcia-Hernandez, P. Garcia-Lario +5
We present the Spitzer/IRS spectra of 157 compact Galactic PNe. These young PNe provide insight on the effects of dust in early post-AGB evolution, before much of the dust is alter…
The Chemical composition of the post-AGB F-supergiant CRL 2688
Miho N. Ishigaki, Mudumba Parthasarathy, Bacham E. Reddy +5
We present an analysis of a high resolution (R~50,000) optical spectrum of the central region of the proto-planetary nebula CRL 2688. This object is thought to have recently moved…
The Interaction of Asymptotic Giant Branch Stars with the Interstellar Medium
Eva Villaver, Arturo Manchado, Guillermo Garcia-Segura
We study the hydrodynamical behavior of the gas expelled by moving Asymptotic Giant Branch Stars interacting with the ISM. Our models follow the wind modulations prescribed by stel…
