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…
The absolute age of the globular cluster M15 using near-infrared adaptive optics images from PISCES/LBT
M. Monelli, V. Testa, G. Bono +26
We present deep near-infrared (NIR) J, Ks photometry of the old, metal-poor Galactic globular cluster M\,15 obtained with images collected with the LUCI1 and PISCES cameras availab…
Probing the MSP prenatal stage: the optical identification of the X-ray burster EXO 1745-248 in Terzan 5
F. R. Ferraro, C. Pallanca, B. Lanzoni +5
We report on the optical identification of the neutron star burster EXO 1745-248 in Terzan 5. The identification was performed by exploiting HST/ACS images acquired in Director's D…
