    On the Dynamics of Bright Features in Sunspot Umbrae
    Time series of white-light pictures of the sunspot NOAA 7522, obtained at the Swedish Vacuum Solar Telescope (La Palma), were analyzed to study the proper...

    On the early evolution of Local Group dwarf galaxy types: star formation and supernova feedback
    According to star formation histories (SFHs), Local Group dwarf galaxies can be broadly classified in two types: those forming most of their stars before z = 2...

    On the effect of discrete numbers of stars in chemical evolution models
    We examine the impact of discrete numbers of stars in stellar populations on the results of Chemical Evolution Models. We explore the resulting dispersion in...
  • Publication
    On the effects of ion-neutral interactions in solar plasmas
    Solar photosphere and chromosphere are composed of weakly ionized plasma for which collisional coupling decreases with height. This implies a breakdown of some...
  • Publication
    On the Effects of the Evolution of Microbial Mats and Land Plants on the Earth as a Planet. Photometric and Spectroscopic Light Curves of Paleo-Earths
    Understanding the spectral and photometric variability of the Earth and the rest of the solar system planets has become of utmost importance for the future...
  • Publication
    On the electron temperatures in high-metallicity HII regions
    The electron temperatures of high-metallicity [12 + log(O/H) > 8.2] HII regions have been studied. The empirical flux-flux relations which express the nebular...
  • Publication
    On the Energy Balance of Solar Active Regions
    Ground-based observations of the sunspot irradiance deficit Ψ and the excess by facular regions in the period 1989 June 3-15 are analyzed using photometric...
  • Publication
    On the Environmental Dependence of the Cluster Galaxy Assembly Timescale
    We present estimates of CN and Mg overabundances with respect to Fe for early-type galaxies in eight clusters over a range of richness and morphology. Spectra...

    On the estimation of galaxy structural parameters: the Sérsic model
    This paper addresses some questions which have arisen from the use of the Sérsic r1/n law in modelling the luminosity profiles of early-type galaxies. The first...
