We present an extensive spectroscopic investigation of evolved old- and intermediate-age stellar tracers of the Carina dSph galaxy. We discuss the approach we...
On the chemical composition of the Milky Way outermost disc
The knowledge of the chemical distribution towards the Galactic anticentre is a powerful method for understanding the history of formation and evolution of the...
On the circumstellar effects on the Li and Ca abundances in massive Galactic O-rich AGB stars
We explore the circumstellar effects on the Li and Ca abundances determination in a complete sample of massive Galactic AGB stars. The Li abundance is an...
On the classification of ultra-compact nuclear rings
Ultra-compact nuclear rings (UCNRs) can be defined as those galactic circumnuclear rings with a radius inferior to 200 parsecs [1]. Because very high spatial...
On the colors of barlenses and their link to B/P bulges
Barlenses are morphological features present in barred galaxies with morphological types between S0 and Sb. Recently, they have been suggested to be the more...
On the continuum intensity-magnetic field relation along the decay phase of sunspots
A continuum intensity-magnetic field distributions are presented for a decaying sunspot. It is shown that a very simple model accounts for the observed...
On The Cooling Tails Of Thermonuclear X-ray Bursts: News From Terzan 5
The neutron star transient and 11 Hz X-ray pulsar IGR J17480-2446, recently discovered in the globular cluster Terzan 5, showed unprecedented bursting activity...
