In the final stages of stellar evolution low- to intermediate-mass stars lose their envelope in increasingly massive stellar winds.

OCTOCAM is a high time-resolution multi-channel instrument that is being proposed for the 10.4m GTC telescope. It will perform simultaneous observations in 8 bands, covering the complete spectrum from the ultraviolet (u-band) to the near infrared (K-band) in a single exposure.

This is a talk I gave last October in Freiburg as the opening key-note lecture of the "1st EAST-ATST Workshop".

The Galactic center is a unique target for studying the properties of the nuclei of galaxies in general. The supermassive black hole, Sagittarius A*, that is located at the dynamical center of the Milky Way is surrounded by the densest and most massive star cluster of our Galaxy.

High spectral resolution evolutionary synthesis models have become a routinely used ingredient in extragalactic work, and as such deserve thorough testing. Star clusters are ideal laboratories for such tests.

In this talk, I present a review of the current status of the very recent line of research linking stellar seismology and exoplanet search. I give a summary of the main exoplanet searching techniques and a general overview of stellar seismology.

Nowadays, following years of technological development, Virtual Observatory standards, resources, and services became powerful enough to help astronomers making real science on everyday basis.

I will present new results on the integrated stellar populations of bulges, bars and disks of spiral galaxies from long-slit spectroscopic observations.

The Fermi Large Area Telescope (Fermi LAT) is a pair conversion telescope sensitive to photons in the energy range 30 MeV to >300 GeV. It was launched on June 11th 2008 and has now been successfully operating for over a year and made breakthrough discoveries in high energy astrophysics.

I present a large-scale spectral survey that is currently obtaining spectra of all known Galactic O stars down to B=13 with R=3000.

Relativistic jets in AGN are the most energetic and among the most powerful astrophysical objects known so far.

High-resolution radio observations of the nuclear regions of Luminous and Ultraluminous Infrared Galaxies (ULIRGs) have shown that their radio structure consists of a compact high surface-brightness central radio source inmersed in a diffuse low brightness circumnuclear halo.

We'll describe the design and science case for the XMS spectrograph at the prime focus of the 3.5-m Calar Alto telescope that can deliver at least 4000 MOS slits simultaneously over a 1-deg field.

After a short introduction to modern infrared long baseline interferometry, I will present the results of two actual projects of mine, dealing with dust around stars and AGN.

GROND stands for Gamma-Ray Burst Optical/Near-Infrared Detector. It is a 7-channel imager developed by the Max-Planck-Institut for extraterrestrial Physics in Garching, Germany, with contributions from the Thueringer Landessternwarte Tautenburg, Germany.

CARMENES is a study for a next-generation instrument for the 3.5m telescope at the Calar Alto Observatory that will be built by an international consortium. CARMENES stands for Calar Alto high-Resolution search for M dwarfs with Exo-Earths with a Near-infrared Echelle Spectrograph.

Based on talks presented at the "Jornada ESO 2009", held on 22 September 2009, I will provide a brief overview of some statistical data related to ESO and particularly the role of Spain within ESO.

We will present the current status of the PANIC project. This instrument will be the first to be built inside the Spanish-German consortium signed between MPIA and IAA for the development of new instrumentation for the Calar Alto Observatory.
