Optical and Infrared Observations of the X-ray source 1WGA J1713.43949 in the G347.3-0.5 SNR
R. P. Mignani, S. Zaggia, A. De Luca +3
X-ray observations unveiled the existence of enigmatic point-like sources at the centre of young supernova remnants (SNRs). These sources, dubbed Central Compact Objects (CCOs), ar…
VLT observations of Compact Central Objects
R. P. Mignani, S. Zaggia, D. Dobrzycka +4
We present the first results of our VLT observation campaign of the Central Compact Objects (CCOs) in SNRs RX J085201.4-461753 (Vela Jr), 1E 1648-5051 (RCW 103) and RX J171328.4-39…
VLT observations of the Central Compact Object in the Vela Jr. supernova remnant
R. P. Mignani, A. De Luca, S. Zaggia +4
X-ray observations have unveiled the existence of enigmatic point-like sources at the center of young (a few kyrs) supernova remnants. These sources, known as Central Compact Objec…
The blue plume population in dwarf spheroidal galaxies: genuine blue stragglers or young stellar population?
Y. Momany, E. V. Held, I. Saviane +3
Abridged... Blue stragglers (BSS) are thought to be the product of either primordial or collisional binary systems. In the context of dwarf spheroidal galaxies it is hard to firmly…
The Ital-FLAMES survey of the Sagittarius dwarf Spheroidal galaxy. I. Chemical abundances of bright RGB stars
L. Monaco, M. Bellazzini, P. Bonifacio +5
We present iron and element (Mg, Ca, Ti) abundances for a sample of 15 Red Giant Branch stars belonging to the main body of the Sagittarius dwarf Spheroidal galaxy. Abundances…
Family ties: abundances in Terzan 7, a Sgr dSph globular cluster
L. Sbordone, P. Bonifacio, G. Marconi +2
We study the chemical composition of 5 giant stars in the globular cluster Terzan 7 associated with the Sagittarius dwarf spheroidal galaxy (Sgr dSph), based on high resolution UVE…
