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…
Distance scale and variable stars in Local Group Galaxies: LMC and Fornax
M. Maio, L. Baldacci, G. Clementini +10
We briefly review our photometric and spectroscopic study of RR Lyrae variable stars in the bar of the Large Magellanic Cloud (LMC), that allowed us to reconcile the so-called "sho…
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…
Variable Stars in the LMC: the Photometric Catalogue
M. Maio, G. Clementini, A. Bragaglia +3
New B, V, I photometry was obtained for a sample of 152 variables (125 RR Lyrae's, 4 anomalous Cepheids, 11 classical Cepheids, 11 eclipsing binaries and a delta Scuti star) in two…
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…
