Rubidium-Rich Asymptotic Giant Branch Stars
D. A. Garcia-Hernandez, P. Garcia-Lario, B. Plez +3
A long debated issue concerning the nucleosynthesis of neutron-rich elements in Asymptotic Giant Branch (AGB) stars is the identification of the neutron source. We report intermedi…
Lithium and zirconium abundances in massive Galactic O-rich AGB stars
D. A. Garcia-Hernandez, P. Garcia-Lario, B. Plez +4
Lithium and zirconium abundances (the latter taken as representative for s-process enrichment) are determined for a large sample of massive Galactic O-rich AGB stars, for which hig…
A spectroscopic atlas of post-AGB stars and planetary nebulae selected from the IRAS Point Source Catalogue
O. Suarez, P. Garcia-Lario, A. Manchado +3
Aims: We study the optical spectral properties of a sample of stars showing far infrared colours similar to those of well-known planetary nebulae. The large majority of them were u…
Planetary Nebula Abundances and Morphology: Probing the Chemical Evolution of the Milky Way
L. Stanghellini, A. M. Guerrero, K. Cunha +2
This paper presents a homogeneous study of abundances in a sample of 79 northern galactic planetary nebulae whose morphological classes have been uniformly determined. Ionic abunda…
The Dynamical Evolution of Planetary Nebulae After the Fast Wind
G. Garcia-Segura, J. A. Lopez, W. Steffen +2
In this paper we explore the dynamics of ionization bounded planetary nebulae after the termination of the fast stellar wind. When the stellar wind becomes negligible, the hot, sho…
Spitzer Spectra of Magellanic Cloud PNe
L. Stanghellini, P. Garcia Lario, A. Manchado +4
Planetary nebulae (PNe) in the Magellanic Clouds (LMC, SMC) offer a unique opportunity to study both the population and evolution of low- and intermediate-mass stars in an environm…
