    A Study of Gravitational Lens Chromaticity with the Hubble Space Telescope
    We report Hubble Space Telescope observations of six gravitational lenses with the Advanced Camera for Surveys. We measured the flux ratios between the lensed...

    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 15-μm quasars in the ELAIS N1 and N2 fields
    This paper discusses the properties of the European Large Area ISO Survey (ELAIS) 15-μm quasars and tries to establish a robust method of quasar selection for...

    A study of the behaviour of the NaI/KI column density ratio in the interstellar medium using the Na ultraviolet doublet
    Here we make a new study of the behaviour of the NaI/KI column density ratio in the interstellar medium, using a sample of new observations of 28 stars obtained...

    A Study of the Binary GR Tauri from Optical and Infrared Observations
    Visual and infrared light curves of the noncontact, short period, close binary system UR Tauri were obtained in 1992 November. A new ephemeris of the binary is...

    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 color-magnitude diagrams and luminosity functions of the two LMC clusters NGC 2134 and NGC 2249 with the new radiative opacities
    We present Johnson CCD photometry in the B and V passbands for the stellar content of two intermediate age star clusters of the Large Magellanic Cloud (LMC)...

    A Study of the Correlation between the Amplification of the Fe Kα Line and the X-Ray Continuum of Quasars due to Microlensing
    The observed enhancement of the Fe Kα line in three gravitationally lensed QSOs (MG J0414+0534, QSO 2237+0305, and H1413+117) is interpreted in terms of...

    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...
