CS 22957-027: A carbon-rich extremely-metal-poor star
P. Bonifacio, P. Molaro, T. C. Beers +1
We present a high-resolution spectroscopic analysis of the extremely-metal-poor star CS 22957-027, which Beers et al (1992) noted to exhibit a rather strong G-band. For Teff = 4839…
The absorption system towards PKS 0118-272: A candidate Damped Ly system at low redshift
G. Vladilo, M. Centurion, R. Falomo +1
We present a spectroscopic and imaging study of the z=0.558 MgII absorption system towards the BL Lac PKS 0118-272. At the absorber redshift we detect lines of the low ionization s…
Abundances of Big Bang elements
Paolo Molaro
In this paper we review the present status of observations of the Big Bang elements D, 3He, 4He and 7Li and of their extrapolation to the primordial values. It is shown that, withi…
The stellar content of the Sagittarius Dwarf Galaxy
G. Marconi, R. Buonanno, M. Castellani +4
We present V,I deep CCD photometry for three fields of the dwarf galaxy in Sagittarius (Sgr). One of the fields is centered on the globular cluster NGC 6715 (M54), which lies in on…
