    A new way to measure the distance to NGC1052-DF2
    We have employed a novel way to measure the distance to NGC1052-DF2, using the internal stellar velocity dispersions (σ) of its globular clusters (GCs). We...

    A new α-enhanced super-solar metallicity population
    We performed a uniform and detailed analysis of 1112 high-resolution spectra of FGK dwarfs obtained with the HARPS spectrograph at the ESO 3.6 m telescope (La...

    A new, evolved bipolar planetary nebula.
    Optical imaging and spectroscopy reveal that the ionised region No.252 in the list of Marsalkowa (1974Ap&SS..27....3M), whose photograph is presented in the `...

    A newly identified galaxy group thanks to tidal streams of intragroup light
    Context. In the accretion-driven growth scenario, part of the intracluster light is formed in the group environment. Aims: We report the serendipitous discovery...

    A non-axisymmetric potential for the Milky Way disk
    We provide a purely dynamical global map of the non-axisymmetric structure of the Milky Way disk. For this, we exploited the information contained within the in...

    A novel framework for semi-Bayesian radial velocities through template matching
    Context. The ability to detect and characterise an increasing variety of exoplanets has been made possible by the continuous development of stable, high...

    A numerical approach for modelling the polarisation signals of strong resonance lines with partial frequency redistribution: Applications to two-term atoms and plane-parallel atmospheres
    Aims. The main goal of this paper is to present an accurate and efficient numerical strategy for solving the radiative transfer problem for polarised radiation...

    A PCA approach to stellar effective temperatures
    Context. The derivation of the effective temperature of a star is a critical first step in a detailed spectroscopic analysis. Spectroscopic methods suffer from...

    A peculiar Of star in the Local Group galaxy IC 1613
    Context. Results from the theory of radiatively driven winds are nowadays incorporated in stellar evolutionary and population synthesis models, and are used in...
