The infrared excess shown by white dwarfs can be an indicator of a low-mass substellar companion, like a brown dwarf or even an exoplanet. In this work, we...

We present the main results derived from a chemical analysis carried out on a large sample of galactic O-rich AGB stars using high resolution optical...

We have measured the emission line profiles in Hα from populations of HII regions in nearby spiral galaxies, and extracted their non-thermal line widths. These...

The authors present results of a search for wide companions to halo subdwarfs of known metallicity. They have taken CCD I-band frames in order to detect faint...

The FastCam instrument, jointly developed by the IAC and the UPCT, allows, in real-time, acquisition, selection and storage of images with a resolution that...

Ursa Minor (UMi) is one of the closest satellites of the Milky Way (d=69 kpc). It is possibly a disrupted dSph interacting with the external Galactic halo. This...

We present optical photometry of the Carina Dwarf Spheroidal (dSph) Galaxy. Data have been collected with CCD mosaic cameras available at the 2.2m ESO/MPI and...

The use of classical techniques for neutron flux measurements in nuclear reactors involves the switching between several detection chains as the power grows up...

I present the status and the recent results of the QUIJOTE (Q-U-I JOint TEnerife) experiment. QUIJOTE is a project that operates from the Teide Observatory...
