    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...

    A study of the galaxy redshift distribution towards the cosmic microwave background cold spot in the Corona Borealis supercluster
    We present a study of the spatial and redshift distributions of Sloan Digital Sky Survey (SDSS) galaxies towards the position of CrB-H, a very deep and extended...

    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 Near-Ultraviolet Spectrum of Vega
    UV, optical, and near-IR spectra of Vega have been combined to test our understanding of stellar atmospheric opacities and to examine the possibility of...
