    A 3D view of the Hyades stellar and sub-stellar population
    Aims: Our scientific goal is to provide a 3D map of the nearest open cluster to the Sun, the Hyades, combining the recent release of Gaia astrometric data...
  • Publication
    A 5D view of the α Per, Pleiades, and Praesepe clusters
    Aims: Our scientific goal is to provide revised membership lists of the α Per, Pleiades, and Praesepe clusters exploiting the second data release of Gaia and...

    A 600 kpc complex radio source at the center of Abell 3718 discovered by the EMU and POSSUM surveys
    Context. Multifrequency studies of galaxy clusters are crucial for inferring their dynamical states and physics. Moreover, these studies allow us to investigate...

    A Bayesian estimation of the Milky Way's circular velocity curve using Gaia DR3
    Aims: Our goal is to calculate the circular velocity curve of the Milky Way, along with corresponding uncertainties that quantify various sources of systematic...

    A biconical ionised gas outflow and evidence of positive feedback in NGC 7172 uncovered by MIRI/JWST
    We present observations of the type-2 Seyfert NGC 7172 obtained with the medium-resolution spectrometer (MRS) of the Mid-Infrared Instrument (MIRI) on board the...

    A binary merger origin for inflated hot Jupiter planets
    We hypothesize that hot Jupiters with inflated sizes represent a separate planet formation channel, the merging of two low-mass stars. We show that the...

    A bipolar-outflow object in the field of M 36.
    We have discovered an object in the field of the Galactic open cluster [1]36 which exhibits a nebulous tail-like structure and a high velocity outflow. We first...

    A boxy bulge in the Milky Way. Inversion of the stellar statistics equation with 2MASS data
    Inverting the stellar statistics equation from 2MASS star counts, we obtain the 3D density distribution of the Galactic bulge as well as its luminosity function...

    A calibration of the Rossby number from asteroseismology
    Stellar activity and rotation are tightly related in a dynamo process. Our understanding of this mechanism is mainly limited by our capability of inferring the...
