The Outer Structure of Galactic Disks: Connections Between Bars, Disks, and Environments
Surface brightness profiles for early type (S0-Sb) disks exhibit three main classes (Type I, II, and III). Type II profiles are more common in barred galaxies...
The outflows from the symbiotic nebulae He 2--147 and HM SGE
Symbiotic stars, which are interacting binary stars usually composed by a late type giant and a very hot/luminous white dwarf, are a powerful laboratory to...
The outskirts of spiral galaxies: probing stellar migration theory
One of the most outstanding predictions of the radial migration theory was a progressive increase in the age of the stellar populations toward the galaxy...
The outskirts of spiral galaxies: touching stellar halos at z˜0 and z˜1
Taking advantage of ultra-deep imaging of SDSS Stripe82 and the Hubble Ultra Deep Field by HST, we explore the properties of stellar halos at two relevant...
The oversampling mode for CoRoT exo-field observations
CoRoT (Convection, Rotation and planetary Transits) is a satellite mission led by CNES. CoRot has been successfully launched on December 27th of 2006. One of...
The p-mode spectrum measured in intensity: from 1996 to 2000
VIRGO-SPM is a helioseismic instrument on board SOHO that observe the disk-integrated sunlight irradiance at three different colours (red, green and blue). In...
