    The post-common-envelope, binary central star of the planetary nebula Hen 2-11
    We present a detailed photometric study of the central star system of the planetary nebula Hen 2-11, selected for study because of its low-ionisation filaments...

    The power spectrum of solar convection flows from high-resolution observations and 3D simulations
    Context. Understanding solar surface magnetoconvection requires the study of the Fourier spectra of the velocity fields. Nowadays, observations are available...

    The pre-main sequence spectroscopic binary UZ Tau East: Improved orbital parameters and accretion phase dependence
    We present radial-velocity measurements obtained using high- and intermediate-resolution spectroscopic observations of the classical T Tauri star UZ Tau East...

    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 Inner Galaxy Survey (PIGS): IX. The largest detailed chemical analysis of very metal-poor stars in the Sagittarius dwarf galaxy
    The most metal-poor stars provide valuable insights into the early chemical enrichment history of a system, carrying the chemical imprints of the first...

    The pristine nature of SMSS 1605−1443 revealed by ESPRESSO
    Context. SMSS J160540.18−144323.1 is the carbon-enhanced metal-poor (CEMP) star with the lowest iron abundance ever measured, [Fe/H] = −6.2, which was first...

    The Pristine survey: XXIII. Data Release 1 and an all-sky metallicity catalogue based on Gaia DR3 BP/RP spectro-photometry
    We used the spectro-photometric information of ∼219 million stars from Gaia's Data Release 3 (DR3) to calculate synthetic, narrowband, metallicity-sensitive...

    The Pristine survey: XXIV. The Galactic underdogs: Dynamic tales of a Milky Way metal-poor population
    Context. Metal-poor stars hold key information on the early Milky Way. Through the identification and characterisation of substructures, one can understand...

    The pulsation modes of the pre-white dwarf PG 1159-035
    Context: PG 1159-035, a pre-white dwarf with Teff≃ 140 000 K, is the prototype of both two classes: the PG 1159 spectroscopic class and the DOV pulsating class...
