    On the estimation of galaxy structural parameters: the Sérsic model
    This paper addresses some questions which have arisen from the use of the Sérsic r1/n law in modelling the luminosity profiles of early-type galaxies. The first...

    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...

    On the Extreme Stationary Outflows from Super Star Clusters: From Superwinds to Supernebulae and Further Massive Star Formation
    Here we discuss the properties of star cluster winds in the supercritical, catastrophic cooling regime. We demonstrate that catastrophic cooling inhibits...

    On the Feedback from Super Stellar Clusters. I. The Structure of Giant H II Regions and H II Galaxies
    We review the structural properties of giant extragalactic H II regions and H II galaxies based on two-dimensional hydrodynamic calculations and propose an...

    On the functional form of the metallicity-giant planet correlation
    Context. It is generally accepted that the presence of a giant planet is strongly dependent on the stellar metallicity. A stellar mass dependence has also been...

    On the HU Aquarii planetary system hypothesis
    In this paper, we investigate the eclipse timing of the polar binary HU Aquarii that has been observed for almost two decades. Recently, Qian et al. attributed...
