    A principal component analysis approach to the star formation history of elliptical galaxies in compact groups
    Environmental differences in the stellar populations of early-type galaxies are explored using principal component analysis (PCA), focusing on differences...

    A pristine record of outer Solar System materials from asteroid Ryugu's returned sample
    Volatile and organic-rich C-type asteroids may have been one of the main sources of Earth's water. Our best insight into their chemistry is currently provided...

    A probabilistic deep learning model to distinguish cusps and cores in dwarf galaxies
    Numerical simulations within a cold dark matter (DM) cosmology form haloes whose density profiles have a steep inner slope ('cusp'), yet observations of...

    A proposal for a low instrumental polarization coude telescope
    A technique for obtaining an ideal two-mirror coude system with no instrumental polarization is described. A half-wave plate positioned between the two mirrors...

    A proposal for a low instrumental polarization coude telescope. II. The German Gregory-Coude Telescope at the Observatorio del Teide.
    We have put into practice the technique to minimize the instrumental polarization (IP) of coude telescopes proposed by Martinez Pillet & Sanchez Almeida (1991)...

    A proto brown dwarf candidate in Taurus
    Aims. We search for brown dwarfs at the Class 0/I evolutionary stage, or proto brown dwarfs. Methods: We present a multi wavelength study, ranging from optical...

    A puffy polar planet. The low density, hot Jupiter TOI-640 b is on a polar orbit
    TOI-640 b is a hot, puffy Jupiter with a mass of 0.57 ± 0.02 M J and radius of 1.72 ± 0.05 R J, orbiting a slightly evolved F-type star with a separation of 6...

    A pulsating white dwarf in an eclipsing binary
    White dwarfs are the burnt-out cores of Sun-like stars and are the fate of 97 per cent of the stars in our Galaxy. The internal structure and composition of...
