Discovery of another peculiar radial distribution of Blue Stragglers in Globular Clusters: The case of 47 Tuc
Francesco R. Ferraro, Giacomo Beccari, Robert T. Rood +3
We have used high resolution WFPC2-HST and wide field ground-based observations to construct a catalog of blue straggler stars (BSS) in the globular cluster 47 Tuc spanning the ent…
The chemical composition of the peculiar companion to the millisecond pulsar in NGC 6397
E. Sabbi, R. G. Gratton, A. Bragaglia +4
We present the chemical composition of the bright companion to the millisecond pulsar J1740-5340 in NGC 6397, based on high resolution spectra. Though the large rotation velocity o…
The Helium White Dwarf orbiting the Millisecond Pulsar in the halo of the Globular Cluster NGC 6752
Francesco R. Ferraro, Andrea Possenti, Elena Sabbi +1
We have used deep high-resolution multiband images taken at the ESO Very Large Telescope to identify the optical binary companion to the millisecond pulsar (PSR J1911-5958A) locate…
The puzzling dynamical status of the core of the globular cluster NGC 6752
F. R. Ferraro, A. Possenti, E. Sabbi +4
We have used high resolution WFPC2-HST and ground based Wide Field images to determine the center of gravity and construct an extended radial density and brightness profile of the…
The complex Halpha line profile of the bright companion to PSR J1740-5340 in NGC 6397
E. Sabbi, R. Gratton, F. R. Ferraro +4
We present a detailed study of the Halpha and He I spectral features of COM J1740-5340 (the companion to PSR J1740-5340 in the Galactic Globular Cluster NGC 6397), exploiting a ser…
Accurate mass ratio and heating effects in the dual-line millisecond binary pulsar in NGC 6397
F. R. Ferraro, E. Sabbi, R. Gratton +4
By means of high-resolution spectra we have measured radial velocities of the companion (hereafter COM J1740-5340) to the eclipsing millisecond pulsar PSR J1740-5340 in the Galacti…
