Detailed chemical abundance analysis of the thick disk star cluster Gaia 1
Andreas Koch, Terese T. Hansen, Andrea Kunder
Star clusters, particularly those objects in the disk-bulge-halo interface are as of yet poorly charted, albeit carrying important information about the formation and the structure…
Spectroscopic confirmation of the low-latitude object FSR 1716 as an old globular cluster
Andreas Koch, Andrea Kunder, Jennifer Wojno
Star clusters are invaluable tracers of the Galactic components and the discovery and characterization of low-mass stellar systems can be used to appraise their prevailing disrupti…
Abundance analysis of a CEMP-no star in the Carina dwarf spheroidal galaxy
A. Susmitha, A. Koch, T. Sivarani
Carbon-enhanced metal-poor (CEMP) stars bear important imprints of the early chemical enrichment of any stellar system. While these stars are known to exist in copious amounts in t…
The binary fraction of stars in dwarf galaxies: the case of Leo II
Meghin Spencer, Mario Mateo, Matthew Walker +4
We combine precision radial velocity data from four different published works of the stars in the Leo II dwarf spheroidal galaxy. This yields a dataset that spans 19 years, has 14…
The Gaia-ESO Survey: Galactic evolution of sulphur and zinc
S. Duffau, E. Caffau, L. Sbordone +48
Due to their volatile nature, when sulfur and zinc are observed in external galaxies, their determined abundances represent the gas-phase abundances in the interstellar medium. Thi…
Galactic Pal-eontology: Abundance Analysis of the Disrupting Globular Cluster Palomar 5
Andreas Koch, Patrick Côté
We present a chemical abundance analysis of the tidally disrupted globular cluster (GC) Palomar 5. By co-adding high-resolution spectra of 15 member stars from the cluster's main b…
