ESPRESSO: projecting a rocky exoplanet hunter for the VLT
ESPRESSO is a high-resolution, highly stable spectrograph for the VLT. It will inherit and enhance most capabilities from HARPS and UVES, combining both...
ESPRESSO: the Echelle spectrograph for rocky exoplanets and stable spectroscopic observations
ESPRESSO, the Echelle SPectrograph for Rocky Exoplanets and Stable Spectroscopic Observations, will combine the efficiency of modern echelle spectrograph design...
ESPRESSO is the next generation ground based European exoplanets hunter. It will combine the efficiency of modern echelle spectrograph with extreme radial...
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) aims to significantly improve our capabilities to observe the solar chromosphere and understanding the solar chromosphere...
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...
