    The pre-main-sequence binary HK Ori: spectro-astrometry and EXPORT data
    In this paper we present multi-epoch observations of the pre-main-sequence binary HK Ori. These data have been drawn from the EXPORT data base and are...

    The Present and Future of Planetary Nebula Research. A White Paper by the IAU Planetary Nebula Working Group
    We present a summary of current research on planetary nebulae and their central stars, and related subjects such as atomic processes in ionized nebulae, AGB and...

    The Pressure-confined Wind of the Massive and Compact Super Star Cluster M82-A1
    The observed parameters of the young super star cluster M82-A1 and its associated compact H II region are here shown to indicate a low heating efficiency or...

    The primordial helium abundance and the number of neutrino families
    Based on observations of HII regions and on the new computations of the recombination coefficients of the HeI lines by Porter el al. we obtain a primordial...

    The Principle of Maximum Entropy and the Distribution of Mass in Galaxies
    We do not have a final answer to the question of why galaxies choose a particular internal mass distribution. Here we examine whether the distribution is set by...

    The principle of maximum entropy explains the cores observed in the mass distribution of dwarf galaxies
    Cold dark matter (CDM) simulations predict a central cusp in the mass distribution of galaxies. This prediction is in stark contrast with observations of dwarf...

    The Pristine dwarf galaxy survey - IV. Probing the outskirts of the dwarf galaxy Boötes I
    We present a new spectroscopic study of the dwarf galaxy Boötes I (Boo I) with data from the Anglo-Australian Telescope and its AAOmega spectrograph together...
