Robust ellipticity measurements of 29 Galactic globular clusters
Laurane Fréour, Ellen Leitinger, Elena Pancino +2
Globular clusters (GCs) exhibit varying degrees of flattening (ellipticity), which may provide insight into their internal dynamics and evolution histories. Commonly used methods t…
Revisiting the near infrared Calcium triplet as metallicity indicator
M. Navabi, R. Carrera, N. E. D. Noël +3
The near-infrared Calcium II Triplet (CaT), around 850nm, is a key metallicity indicator for red giant stars. We present a revised [Fe/H] calibration as a function of CaT line stre…
The Preliminary Mauve Science Programme: Science themes identified for the first year of operations
Mauve Science Collaboration, Marcel Agueros, Don Dixon +22
Mauve is a low-cost small satellite developed and operated by Blue Skies Space Ltd. The payload features a 13 cm telescope connected with a fibre that feeds into a UV-Vis spectrome…
A chemical trompe-l'œil: no iron spread in the globular cluster M22
A. Mucciarelli, E. Lapenna, D. Massari +5
We present the analysis of high-resolution spectra obtained with UVES and UVES-FLAMES at the Very Large Telescope of 17 giants in the globular cluster M22, a stellar system suspect…
Carbon and nitrogen abundances of stellar populations in the globular cluster M 2
C. Lardo, E. Pancino, A Mucciarelli +1
We present CH and CN index analysis and C and N abundance calculations based on the low-resolution blue spectra of red giant branch (RGB) stars in the Galactic globular cluster NGC…
Chemical abundance analysis of the Open Clusters Berkeley 32, NGC 752, Hyades and Praesepe
R. Carrera, E. Pancino
Context. Open clusters are ideal test particles to study the chemical evolution of the Galactic disc. However the existing high-resolution abundance determinations, not only of [Fe…
Low-resolution spectroscopy of main sequence stars belonging to 12 Galactic globular clusters. I. CH and CN band strength variations
E. Pancino, M. Rejkuba, M. Zoccali +1
Globular clusters show abundance variations for light elements that are not yet well understood. The preferred explanation involves a self-enrichment scenario, with two subsequent…
Chemical abundance analysis of the Open Clusters Cr110, NGC2099 (M37), NGC2420, NGC7789 and M67 (NGC2682)
E. Pancino, R. Carrera, E. Rossetti +1
(Abridged) The present number of Galactic Open Clusters that have high-resolution abundance determinations, not only of [Fe/H], but also of other key elements, is largely insuffici…
