    On the estimation of stellar parameters with uncertainty prediction from Generative Artificial Neural Networks: application to Gaia RVS simulated spectra
    Aims: We present an innovative artificial neural network (ANN) architecture, called Generative ANN (GANN), that computes the forward model, that is it learns...

    On the Eulerian Approach to the Evolution of Large-Scale Structures
    Within the classical Eulerian theory of gravitational instability, and in an Omega = 1 universe, we introduce a method for obtaining iterative solutions for the...
  • Publication
    On the evolution of ejecta fragments in compact supernova remnants.
    The authors examine the evolution of inhomogeneities (fragments) of supernova ejecta in compact supernova remnants by means of hydrodynamical modelling and...
  • Publication
    On the evolution of supernova remnants. II - Two-dimensional calculations of explosions inside pre-existing wind-driven bubbles
    Supernova explosions within wind-driven bubbles are studied with 2D hydrodynamical calculations. Two different density distributions for the ejecta are...
  • Publication
    On the evolution of supernova remnants. III - Off-centred supernova explosions in pre-existing wind-driven bubbles
    It is shown that supernova explosions inside wind-driven cavities created by progenitors moving across the ambient medium result in a large diversity of remnant...

    On the evolutionary status of two very active visual binaries
    HD 36705 (AB Doradus) and HD 155555 (V824 Ara) are two nearby very active cool stars. Both have strong Li I (lambda)6708 resonance lines, implying high surface...

    On the evolutionary status of X-ray selected weak-line T Tauri star candidates in Taurus-Auriga
    We present lithium observations of 35 stars previously reported by Wichmann et al. (1996) to be possible new weak T Tauri stars (WTTS) discovered by ROSAT in...
  • Publication
    On the Existence of the June Lyrid Meteor Shower
    The possible existence of the June Lyrid meteor shower is examined from data in the IMO archive from 1984 to 1997. It is concluded that the activity is weak but...
  • Publication
    On the Extended Structure of the Phoenix Dwarf Galaxy
    We present the star formation history (SFH) and its variations with galactocentric distance for the Local Group dwarf galaxy of Phoenix. They have been derived...
