The stellar host in Blue Compact Dwarf Galaxies: On the need of a 2D fit
In order to characterize the low surface brightness component in blue compact dwarf galaxies, we determine their structural parameters for eight objects by...
The stellar mass growth of bulges and discs across cosmic time
The formation of stellar structures in galaxies is intimately connected to all evolutionary processes. Violent mergers prevent or destroy fragile discs, while...
The stellar occultation by Makemake on 2011 April 23
We have taken advantage of a stellar occultation by the dwarf planet Makemake on 2011 April 23, to determine several of its main physical properties. We present...
The stellar population in the XMM-Newton slew survey
We study X-ray transients from the XMM-Newton slew catalog with focus on the identification of flare stars. We have selected 118 variable X-ray sources from the...
We discuss recent observations of stars located close to the symmetry plane of the Milky Way, and examine them in the context of theories of Galaxy formation...
