    A study of catalogued nearby galaxy clusters in the SDSS-DR4. I. Cluster global properties
    Context: Large surveys such as the Sloan Digital Sky Survey have made large amounts of spectroscopic and photometric data of galaxies available, thereby...

    A study of catalogued nearby galaxy clusters in the SDSS-DR4. II. Cluster substructure
    Context. According to the current cosmological paradigm, large scale structures form hierarchically in the Universe. Clusters of galaxies grow through a...

    A study of correlation between the oscillation amplitude and stellar parameters of delta Scutis in open clusters. Toward selection rules for delta Scuti star oscillations
    In the present work, we study correlations between stellar fundamental parameters and the oscillation amplitude for delta Scuti stars. We present this study for...

    A study of emission lines variability of the active galaxy PKS 0521-365.
    Optical spectrophotometry of the active galaxy PKS 0521-365 over a period of 7 years is reported, together with the analysis of IUE archival spectra. The Hα...

    A study of interacting galaxies from the Arp-Madore catalog: Triggering of star formation and nuclear activity
    We present Gemini Multi-Object Spectrograph (GMOS) spectroscopic observations of 95 galaxies from the Arp & Madore (1987) catalog of peculiar galaxies. These...

    A study of the capabilities for inferring atmospheric information from high-spatial-resolution simulations
    In this work, we study the accuracy that can be achieved when inferring the atmospheric information from realistic numerical magneto-hydrodynamic simulations...

    A study of the effect of rotational mixing on massive stars evolution: surface abundances of Galactic O7-8 giant stars
    Context. Massive star evolution remains only partly constrained. In particular, the exact role of rotation has been questioned by puzzling properties of OB...

    A study of the interplay between ionized gas and star clusters in the central region of NGC 5253 with 2D spectroscopy
    Context. Starbursts are one of the main contributors to the chemical enrichment of the interstellar medium. However, mechanisms governing the interaction...

    A study of the neglected Galactic H ii region NGC 2579 and its companion ESO 370-9
    Context: The Galactic H ii region NGC 2579 has stayed undeservedly unexplored due to identification problems which persisted until recently. Both NGC 2579 and...
