Highlights of Spanish Astrophysics IV ; Proceedings of the Seventh Scientific Meeting of the Spanish Astronomical Society (SEA) held in Barcelona, Spain, September 12-15, 2006

This volume documents the contributions presented at the Seventh Scientific Meeting of the Spanish Astronomical Society (Sociedad Española de Astronomía, SEA). Two plenary sessions of the meeting were devoted to the approved entrance of Spain as a full member of the European Southern Observatory (ESO) and to the imminent first light of the greatest telescope in the world, the GTC (Gran Telescopio de Canarias), milestones that will certainly lead the Spanish Astronomy in the next future.
