    The phase function for stellar acoustic oscillations - IV. Solar-like stars
    In recent years there has been some progress towards detecting solar-like oscillations in stars. The goal of this challenging project is to analyse frequency...

    The phase function for stellar acoustic oscillations. I - Theory
    The influence of the upper layers of a star on p-mode frequencies can be described asymptotically by means of a phase function, which depends essentially only...
  • Publication
    The phase function for stellar acoustic oscillations. II - Effects of filtering
    Frequencies of solar acoustic oscillations can be analyzed asymptotically in terms of a function determined by the sound speed in the bulk of the sun and a...

    The Photo-Astrometric vertical tracer density of the Milky Way - I. The method
    We introduce a method to infer the vertical distribution of stars in the Milky Way using a Poisson likelihood function, with a view to applying our method to...
  • Publication
    The photo-astrometric vertical tracer density of the Milky Way - II. Results from Gaia
    We use Gaia photometry and astrometry to estimate the vertical spatial structure of the Milky Way at the Solar radius, formally accounting for sample...

    The photocentre-AGN displacement: is M87 actually harbouring a displaced supermassive black hole?
    M87 has been identified as a displaced supermassive black hole (SMBH) candidate. We investigated this possibility by a temporal analysis of 12 adaptive-optics...

    The Photodetector Array Camera and Spectrometer (PACS) on the Herschel Space Observatory
    The Photodetector Array Camera and Spectrometer (PACS) is one of the three science instruments on ESA's far infrared and submillimetre observatory. It employs...

    The photometric properties of isolated early-type galaxies
    Isolated galaxies are important because they probe the lowest density regimes inhabited by galaxies. We define a sample of 36 nearby isolated early-type...

    The photosphere and chromosphere of the RS Canum Venaticorum star, II Pegasi. II. A multi-wavelength campaign in August/September 1992
    We describe multi-wavelength, simultaneous observations of the RS CVn star, II Pegasi, most of which were obtained during the first three weeks of September...
