    On the Energy Balance of Solar Active Regions
    Ground-based observations of the sunspot irradiance deficit Ψ and the excess by facular regions in the period 1989 June 3-15 are analyzed using photometric...

    On the Environmental Dependence of the Cluster Galaxy Assembly Timescale
    We present estimates of CN and Mg overabundances with respect to Fe for early-type galaxies in eight clusters over a range of richness and morphology. Spectra...

    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 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...

    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...

    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...
