ESPRESSO: the ultimate rocky exoplanets hunter for the VLT
ESPRESSO, the VLT rocky exoplanets hunter, will combine the efficiency of modern echelle spectrograph with extreme radial-velocity precision. It will be...
The European Solar Telescope (EST) is a project for a 4 meter-class ground-based telescope, to be located in the Canary Islands. The project is promoted by the...
EST: the largest and most sensitive spectropolarimeter
Magnetic field plays a crucial role to understand most phenomena happening in the solar atmosphere. Sunspots, flares, prominences, coronal mass ejections are...
Estabilidad de una mezcla gas-estrellas en un sistema de celdas
We study the process of formation of spiral structure extending the classical Turing's model to the case of a disk of stars and gas with diferencial rotation.
Established and Non-Established Properties of Umbral and Penumbral Fine Structures
Four main aspects of umbral and penumbral fine structures are considered: brightness and morphology, magnetic field, velocity and oscillations. The author...
Establishing a New Order: The Orientation of Roman Towns Built in the Age of Augustus
Urbanism in most areas of Western Europe occurred at the time of the Roman Empire when several hundred new towns were founded, notably under Augustus. Those...
Estimating the Age of Exoplanet Host Stars: Possible Member of the Hyades Supercluster Confirmed by Chemically Tagging
During our detailed study of the kinematics of the know exoplanets hots stars (Montes et al. 2010, Caballero et al. 2010) we have identified possible members of...
