    On the Shape of the Light Profiles of Early Type Galaxies
    We have obtained the best fit to the light profiles of a luminosity- limited sample of elliptical and S0 galaxies with a power law r^1/n^, letting the exponent...

    On the Shape of the Light Profiles of Early Type Galaxies - Part Two - the - Diagram
    We present new evidence against the universality of the de Vaucouleurs r^1/4^ law, considered to be the best empirical formula for fitting the light profiles of...

    On the signatures of flare-induced global waves in the Sun: GOLF and VIRGO observations
    Recently, several efforts have been made to identify the seismic signatures of flares and magnetic activity in the Sun and Sun-like stars. In this work, we have...

    On the solar abundance of indium
    The generally adopted value for the solar abundance of indium is over six times higher than the meteoritic value. We address this discrepancy through numerical...

    On the triple-star origin of the planetary nebula Sh 2-71
    Recent studies have indicated that triple-star systems may play a role in the formation of an appreciable number of planetary nebulae, however, only one triple...

    On the ultra-compact nature of the neutron star system 1RXS J170854.4-321857: insights from X-ray spectroscopy
    The relatively small family of ultra-compact X-ray binary systems is of great interest for many areas of astrophysics. We report on a detailed X-ray spectral...

    On the ultracompact nature of 4U1822-000
    We report the discovery of a periodic modulation in the optical lightcurve of the candidate ultracompact X-ray binary 4U1822-000. Using time-resolved optical...

    On the use of field RR Lyrae as galactic probes - VI. Mixed mode RR Lyrae variables in Fornax and in nearby dwarf galaxies
    We investigate the properties of the mixed-mode (RRd) RR Lyrae (RRL) variables in the Fornax dwarf spheroidal (dSph) galaxy by using B- and V-band time series...

    On the validity of quasi-linear kinematic mean-field electrodynamics in astrophysical flows
    Mean-field theory in its kinematic form with the quasi-linear approximation is widely used for the modelling of the transport of weak magnetic fields in...
