The stellar and substellar mass function in central region of the old open cluster Praesepe from deep LBT observations
Studies of the mass function of open clusters of different ages allow us to study the efficiency with which brown dwarfs are evaporated from clusters to...
The stellar content of a prototype double barred galaxy
High spatial resolution visible and NIR observations of the bar of NGC 5850, a prototype of double barred spirals, together with visible intermediate and high...
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 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...
