    Photometric observations of the Type Ia SN 2002er in UGC 10743
    Extensive light and colour curves for the Type Ia supernova (SN Ia) SN 2002er are presented as part of the European Supernova Collaboration. We have collected...

    Photometric survey, modelling, and scaling of long-period and low-amplitude asteroids
    Context. The available set of spin and shape modelled asteroids is strongly biased against slowly rotating targets and those with low lightcurve amplitudes...

    Photometric Variability of the Disk-integrated Thermal Emission of the Earth
    Here we present an analysis of the global-integrated mid-infrared emission flux of the Earth based on data derived from satellite measurements. We have studied...

    Photometric variability of young brown dwarfs in the σ Orionis open cluster
    We have carried out multi-epoch, time-series differential I-band photometry of a large sample of objects in the south-east region of the young (˜3 Myr), nearby...

    Photometry of high-redshift blended galaxies using deep learning
    The new generation of deep photometric surveys requires unprecedentedly precise shape and photometry measurements of billions of galaxies to achieve their main...

    Photospheric Hanle diagnostic of weak magnetic dipoles in stars
    Aims: We propose and explore a new diagnostic technique based upon the linear polarization emitted in Hanle-sensitive lines in disk-integrated stars where a...

    Photospheric magnetic topology of a north polar region
    Aims: We aim to characterise the magnetism of a large fraction of the north polar region close to a maximum of activity, when the polar regions are reversing...
