  • Publication
    The population of barred galaxies in the local universe. I. Detection and characterisation of bars
    Context: Bars are very common in the centre of the disc galaxies, and they drive the evolution of their structure. The state-of-the-art imaging and redshift...

    The population of variable stars in M54 (NGC6715)
    We present new B, V and I CCD time-series photometry for 177 variable stars in a 13 × 13arcmin2 field centred on the globular cluster M54 (lying at the centre...
  • Publication
    The population, magnitudes, and sizes of Jupiter family comets
    We analyze the sample of measured nuclear magnitudes of the observed Jupiter family (JF) comets (taken as those with orbital periods P 20 years and Tisserand...
  • Publication
    The Possible Ascent of a Closed Magnetic System through the Photosphere
    We present a comprehensive interpretation of the evolution of a small magnetic region observed during its entire disk passage. The vector magnetic field...
  • Publication
    The possible connection between ionization in the atmosphere by cosmic rays and low level clouds
    Recent analysis of monthly mean cloud data from the International Satellite Cloud Climatology Project uncovered a strong correlation between low cloud and the...
  • Publication
    The possible origin of facular brightness in the solar atmosphere
    This paper studies the dependence of the Ca ii H line core brightness on the strength and inclination of the photospheric magnetic field, and on the parameters...
  • Publication
    The post-common envelope central stars of the planetary nebulae Henize 2-155 and Henize 2-161
    We present a study of Hen 2-155 and Hen 2-161, two planetary nebulae which bear striking morphological similarities to other planetary nebulae known to host...
  • Publication
    The post-common-envelope binary central star of the planetary nebula ETHOS 1
    We present a detailed study of the binary central star of the planetary nebula ETHOS 1 (PN G068.1+11.0). Simultaneous modelling of light and radial velocity...
  • Publication
    The post-common-envelope binary central star of the planetary nebula Ou 5: a doubly eclipsing post-red-giant-branch system
    We present a detailed study of the stellar and orbital parameters of the post-common envelope binary central star of the planetary nebula Ou 5. Low-resolution...
