High resolution spectroscopy of the high velocity hot post-AGB star LS III +52 24 (IRAS 22023+5249)
G. Sarkar, D. A. Garcia-Hernandez, M. Parthasarathy +3
The first high-resolution (R~50,000) optical spectrum of the B-type star, LS III +52 24, identified as the optical counterpart of the hot post-AGB candidate IRAS 22023+5249 (I22023…
Molecular processes from the AGB to the PN stage
D. A. Garcia-Hernandez
Many complex organic molecules and inorganic solid-state compounds have been observed in the circumstellar shell of stars (both C-rich and O-rich) in the transition phase between A…
Modeling the dust emission from PN IC418
Christophe Morisset, Ryszard Szczerba, D. A. Garcia-Hernandez +1
We construct a detailed model for the IR dust emission from the PN IC 418. We succeed to reproduce the emission from 2 to 200m. We can determine the amount of emitting dust as w…
The formation of fullerenes: clues from new C60, C70, and (possible) planar C24 detections in Magellanic Cloud Planetary Nebulae
D. A. Garcia-Hernandez, S. Iglesias-Groth, J. A. Acosta-Pulido +6
We present ten new Spitzer detections of fullerenes in Magellanic Cloud Planetary Nebulae, including the first extragalactic detections of the C70 molecule. These new fullerene det…
Morphological classification of post-AGB stars
A. Manchado, D. A. Garcia-Hernandez, E. Villaver +1
We present a complete study of the morphology of post-Asymptotic Giant Branch (AGB) stars. Post-AGB is a very short evolutionary phase between the end of the AGB and the beginning…
Rubidium-rich Asymptotic Giant Branch stars in the Magellanic Clouds
D. A. Garcia-Hernandez
The Magellanic Clouds (MCs) offer a unique opportunity to study the stellar evolution and nucleosynthesis of massive Asymptotic Giant Branch (AGB) stars in low metallicity environm…
