Deuterium astration in the local disc and beyond
Donatella Romano, Monica Tosi, Cristina Chiappini +1
(Abridged) Estimates of the interstellar deuterium abundance span a wide range of values. Here we study the evolution of deuterium in the framework of successful models for the che…
BVI photometry of the very old open cluster Berkeley 17
Angela Bragaglia, Monica Tosi, Gloria Andreuzzi +1
We have obtained BVI CCD imaging of Berkeley 17, an anticentre open cluster that competes with NGC 6791 as the oldest known open cluster. Using the synthetic colour magnitude diagr…
The old anticentre open cluster Berkeley 32: membership and fundamental parameters
V. D'Orazi, A. Bragaglia, M. Tosi +2
We have obtained medium-low resolution spectroscopy and BVI CCD imaging of Berkeley 32, an old open cluster which lies in the anticentre direction. From the radial velocities of 48…
The metallicity of the old open cluster NGC 6791
Raffaele Gratton, Angela Bragaglia, Eugenio Carretta +1
We have observed four red clump stars in the very old and metal-rich open cluster NGC 6791 to derive its metallicity, using the high resolution spectrograph SARG mounted on the TNG…
