Weighing stars: the identification of an Evolved Blue Straggler Star in the globular cluster 47 Tucanae
F. R. Ferraro, E. Lapenna, A. Mucciarelli +4
Globular clusters are known to host peculiar objects, named Blue Straggler Stars (BSSs), significantly heavier than the normal stellar population. While these stars can be easily i…
Chemical analysis of Asymptotic Giant Branch stars in M62
E. Lapenna, A. Mucciarelli, F. R. Ferraro +4
We have collected UVES-FLAMES high-resolution spectra for a sample of 6 asymptotic giant branch (AGB) and 13 red giant branch (RGB) stars in the Galactic globular cluster M62 (NGC6…
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…
Lines and continuum sky emission in the near infrared: observational constraints from deep high spectral resolution spectra with GIANO-TNG
E. Oliva, L. Origlia, S. Scuderi +19
Aims Determining the intensity of lines and continuum airglow emission in the H-band is important for the design of faint-object infrared spectrographs. Existing spectra at low/med…
The origin of the spurious iron spread in the globular cluster NGC 3201
A. Mucciarelli, E. Lapenna, D. Massari +2
NGC 3201 is a globular cluster suspected to have an intrinsic spread in the iron content. We re-analysed a sample of 21 cluster stars observed with UVES-FLAMES at the Very Large Te…
