Analysis of solar velocity data obtained at Izaña (Tenerife) over the years 1981 - 1985, has shown the existence of significant signals in the frequency range...

So far, surface magnetic fields have never been reported on Mira stars, while observational facilities allowing detection and measurement of weak surface fields...

The authors present the preliminary results of a search for near-infrared counterparts of compact H II regions and/or H2O masers in the Galactic Plane, probably...

We discuss methods and preliminary results in a search for variable stars in the Carina dSph galaxy. This galaxy presents a complex star formation history and...

We present deep images on the Hα emission plus an adjacent continuum obtained with OSIRIS/GTC, using the TF red in scanning mode for the Seyfert 2 galaxy Mrk...

We have performed a search for substellar objects as common proper motion companions to young nearby stars (including members of the Young Moving Groups AB...

We report on our on-going proper motion survey of very low-mass (>=5 MJup), ultracool (Teff>=350 K) companions of nearby, field T-type brown dwarfs in the Solar...

Since 1995, more than 140 planets around solar-type stars have been discovered. The great success of the first decade of observational research in exoplanets...
