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

We have conducted a systematic search for stellar disk truncations in disk--like galaxies at intermediate redshift (z

Transient radio emission from X-ray binaries is associated with synchrotron emission from collimated jets that escape the system, and accreting millisecond X-ray pulsars (AMXPs) are no exception. Although jets from black hole X-ray binaries are well-studied, those from neutron star systems appear much fainter, for reasons yet uncertain. Jets are

We present azimuthally-averaged spectral energy distributions (SEDs) from FUV to FIR, as a function of radius, for the galaxies included in the SINGS sample. The radial changes in these SEDs are interpreted in terms of variations of the relative contribution of stars (of different ages), dust and gas.
