    Abell 30 - A binary central star among the born-again planetary nebulae
    Eight planetary nebulae have been identified as 'born-again', a class of object typified by knotty secondary ejecta having low masses (${\sim}10^{-4}$ M ☉) with...

    Abell 41: shaping of a planetary nebula by a binary central star
    We present the first detailed spatiokinematical analysis and modelling of the planetary nebula Abell 41, which is known to contain the well-studied close-binary...

    About Metallicity Variations in the Local Galactic Interstellar Medium
    In this paper we discuss and confront recent results on metallicity variations in the local interstellar medium, obtained from observations of H II regions and...

    About the iron carbonyl complex with C60and C70fullerene: [Fe(CO)4(η2C60)] and [Fe(CO)4(η2C70)]
    The iron carbonyl complexes with C60 and C70 fullerenes were synthesized in high yield by photochemical irradiation of solutions of C60 and C70 in presence of...

    About the p-mode frequency shifts in HD 49933
    We study the frequency dependence of the frequency shifts of the low-degree p modes measured in the F5V star HD 49933, by analyzing the second run of...

    About the rotation of the solar radiative interior
    In the modern era of helioseismology we have a wealth of high-quality data available, e.g., more than 6 years of data collected by the various instruments on...

    Absence of an X-shaped Structure in the Milky Way Bulge Using Mira Variable Stars
    The stellar density distribution of the bulge is analyzed through one of its tracers. We use oxygen-rich Mira variables from the Catchpole et al. survey and...

    Absence of anti-correlations and of baryon acoustic oscillations in the galaxy correlation function from the Sloan Digital Sky Survey data release 7
    Aims: One of the most striking features predicted by standard models of galaxy formation is the presence of anti-correlations in the matter distribution on...

    Absence of nuclear polycyclic aromatic hydrocarbon emission from a compact starburst: The case of the type-2 quasar Mrk 477
    Mrk 477 is the closest type-2 quasar, at a distance of 163 Mpc. This makes it an ideal laboratory for studying the interplay between nuclear activity and star...
