In this work we focus on the evolution of the SFR, metallicity of the gas, and morphology of galaxies at low redshift in search of signs of evolution. We analyzed the evolution of the SFR, metallicity, and morphology, through the mass-metallicity, luminosity-metallicity, SFR-stellar mass, and SFR-metallicity relationships of star-forming galaxies

The site for the future European Extremely Large Telescope (E-ELT) is already known to be Armazones, near Paranal (Chile). The selection was based on a variety of considerations, with an important one being the quality of the atmosphere for the astronomy planned for the ELT. We present an overview of the characterization of the atmospheric

By making use of real information about the continental and oceanic surface distribution of the Earth, and cloudiness data from the International Satellite Cloud Climatology Project (ISCCP), we have studied the large-scale cloudiness behavior according to latitude and surface types (ice, water, vegetation and desert). These empirical relationships

g' and z' photometric time series for the last ~1.6hrs of the transit of KOI 806.2 observed with the Gran Telescopio Canarias at Observatorio del Roque de los Muchachos on the island of La Palma, Spain. The observations occurred on JD 2455740, revealing a transit timing variation of -103.5+/-6.9 minutes. The raw fits files were bias and flat field

We present the detailed chemical abundance patterns of 95 solar analogs, 24 hosting planets and 71 without detected planets, using very high-quality HARPS and UVES spectra. We explore the possibility that the presence of terrestial planets could affect the volatile-to-refratory abundance ratios. We do not see any clear difference between the stars

Using spectropolarimetric data of an Active Region (AR) filament we have carried out inversions in order to infer vector magnetic fields in the photosphere (Si I line) and in the chromosphere (He I line). Our filament lies above the polarity inversion line (PIL) situated close to disk center and presents strong Zeeman-like signatures in both
