Galactic 26Al is believed to be predominantly injected into the ISM from winds and supernovae of massive stars. These stars are typically born in groups and...
Publicación26Al in galaxy regions: massive-star interactions with the ISM
Publicación26Al yields from rotating Wolf-Rayet star models
We present new 26Al stellar yields from rotating Wolf-Rayet stellar models which, at solar metallicity, well reproduce the observed properties of the Wolf-Rayet...
PublicaciónA Massive AGB Star as Source of Short-Lived Nuclei in the Early Solar System
The origin of short-lived radioactive nuclei at the time of the formation of the Sun is a much debated mystery in modern astronomy. We show that abundance...
PublicaciónA Minor-Merger Origin for Inner Disks and Rings in Early-Type Galaxies
Nuclear disks and rings are frequent galaxy substructures, for a wide range of morphological types [from S0 to Sc, see e.g., 1, 2]. We have investigated the...
PublicaciónA search for lithium in cataclysmic binaries.
The discovery of Li in the late type secondary of the black hole binary V404 Cyg has motivated considerable interest in the presence of this light element in...
PublicaciónAn attempt to derive Mg isotopic ratios in carbon stars
We discuss the use of the spectral range near 7570 Å to determine the Mg isotopic ratios in carbon stars using the B'2 Sigma +-X 2 Sigma + system of the MgH...
PublicaciónAn Elemental Assay of Very, Extremely, and Ultra-metal-poor Stars
We present a high-resolution elemental-abundance analysis for a sample of 23 very metal-poor ([Fe/H]
PublicaciónAnisotropy of the cosmic microwave background and primordial nucleosynthesis: observational pillars of big bang cosmology.
The authors review recent results on the anisotropy of the cosmic microwave background and on primordial abundances of light-elements. These two key fields of...
PublicaciónBeryllium and Boron Evolution in the Galaxy
We present a model for the evolution of the light-nuclide abundances in the Galaxy, aimed especially at interpreting the observed beryllium and boron abundances...
