Using data obtained with the ESO-Very Large Telescope, we have performed a deep optical and NIR photometric study of the fields of three Accreting Millisecond X-ray Pulsars (XTE J1814-338, XTE J0929-314 and XTE J1807-294) during quiescence in order to look for the presence of a variable counterpart. If suitable candidates are found, we also carried

The structural parameters of a magnitude-limited sample of 148 unbarred S0-Sb galaxies were derived to study the correlations between bulge and disk parameters as well as the probability distribution function (PDF) of the intrinsic equatorial ellipticity of bulges. A new algorithm (GASP2D) was used to perform the bidimensional bulge-disk

We briefly review the revised classification of the radial surface brightness profiles focusing on the outer disk structure, discussing possible formation scenarios, and posing some open questions.

The progress on the dynamics of the radiative zone by global Doppler velocity measurements aboard SoHO (GOLF+ MDI) and with ground networks (BiSON and GONG) opens a new perspective for solar and stellar physics. It is why we prepare a new generation of solar resonant spectrometer. The objectives of the GOLF-NG instrument and its present status are

We present TCS-CAIN, a NIR survey of the Galactic plane, recently made public at the Instituto de Astrofísica de Canarias, and some results derived from it: with star counts derived directly from it the structure of the inner the Milky Way can be dissected, and with low resolution spectra, (part of a follow-up program), its nature, specifically the

After our report on the flux decay of the neutron star transient SAX J1750.8-2900 (ATel #1662) we have continued monitoring the source with Swift-XRT in order to study its transition to quiescence. In these observations (performed between August 14th. and October 8th.) we detect the source at different flux levels, with the corresponding luminosity
