  • Complex ionization structure and kinematics in the circumnuclear region of NGC 3227
    We present bidimensional spectroscopy of the circumnuclear region of the Seyfert galaxy NGC 3227. The physical and kinematical characteristics of the two gaseous components reported recently by Mediavilla & Arribas are discussed. One of the components seems to be directly related to activity. We propose that it represents gas streaming from the

  • Conformal Factors of Generalized Cosmologies
    We present a study of the properties of radial conformal Killing fields (RCKF) in conformally flat space-times, pointing out its interest in kinematical cosmology. i) Robertson-Walker space-times are characterized as those conformally flat metrics admitting a geodesic RCKF. ii) The conformal factor of space-times that admit a RCKF with homogeneous

  • Connecting the central and global structure of early-type galaxies
    A new empirical model that accurately describes the inner and outer light-profiles of early-type galaxies is presented. This model effectively unites the Sérsic and Nuker models, and in so doing allows one to perform meaningful comparisons between the inner and outer properties of early-type galaxies. New and fundamental connections between a

  • Constraining planet structure and composition from stellar chemistry: trends in different stellar populations
    Context. The chemical composition of stars that have orbiting planets provides important clues about the frequency, architecture, and composition of exoplanet systems. Aims: We explore the possibility that stars from different galactic populations that have different intrinsic abundance ratios may produce planets with a different overall

  • Constraints of a pulsation frequency on stellar parameters in the eclipsing spectroscopic binary system V577 Oph
    We present a preliminary spectroscopic analysis of the binary system V577Oph, observed during the summer of 2007 on the 2.6 m NOT telescope on La Palma. We have obtained time series spectroscopic observations, which show clear binary motion as well as radial velocity variations due to pulsation in the primary star. By modelling the radial

  • Constraints on a Second Planet in the WASP-3 System
    There have been previous hints that the transiting planet WASP-3b is accompanied by a second planet in a nearby orbit, based on small deviations from strict periodicity of the observed transits. Here we present 17 precise radial velocity (RV) measurements and 32 transit light curves that were acquired between 2009 and 2011. These data were used to
