Chemical Evolution of the Galaxy and Supernova Yields after UVES
The atmospheres of stars orbiting around black holes/neutron stars may contain a large amount of α and r-process elements as a result of contamination with the...
Chemical Fingerprinting and Chemical Analysis of Galactic Halo Substructure
We present high-resolution spectroscopic measurements of the abundances of the α-like element titanium (Ti) and s-process elements yttrium (Y) and lanthanum (La...
In this paper we review the current situation regarding the study of the metallicity-giant planet connection. We show that planet-host stars are more metal-rich...
Chemical Signature of Gas-rich disc-disc Mergers at high Redshift
We performed numerical simulations of mergers between gas-rich disc galaxies, which result in the formation of late-type galaxies. Stars formed during the...
Stellar Kinematic Groups are kinematical coherent groups of stars which might share a common origin. These groups spread through the Galaxy over time due to...
Chemical Tagging of Stellar Kinematic Groups: The Hyades Supercluster
Stellar Kinematic Groups are kinematical coherent groups of stars which may share a common origin. These groups spread through the Galaxy over time due to tidal...
Chemical tagging of the Hyades supercluster as a consistency test of stellar kinematic groups
Stellar kinematic groups are kinematically coherent groups of stars that may share a common origin. These groups spread through the Galaxy over time due to...
