We present results on the study of 24 bulges of Sa galaxies observed with the integral-field unit SAURON at the William Herschel Telescope. Here we review some...
Galactic Disk Warps due to Intergalactic Accretion Flows onto the Disk
The accretion of the intergalactic medium onto the gaseous disc is used to explain the generation of galactic warps. A cup-shaped distortion is expected, due to...
We discuss the early evolution of beryllium and oxygen in our Galaxy by comparing abundances of these elements for halo and disk metal-poor stars. Both, O and...
Abundance analysis of Carbon and Nitrogen has been performed in a sample of 32 late F and early G type dwarf metal poor stars in the metallicity range -3.3 [Fe...
