  • Physical properties of the ionized gas and brightness distribution in NGC4736
    In this work we study the galaxy NGC4736, using narrow band interference filters imaging centered at the emission lines {Oii} {3727+3729}, Hβ, {Oiii} {5007}, Hα, {Sii} {6716+6730} and {Siii} {9070} and nearby continua. We have obtained sizes, positions, emission line absolute fluxes, and continua intensities for 90 Hii regions, mainly distributed

  • On the outburst amplitude of the soft X-ray transients
    We find a strong correlation between the optical outburst amplitude and orbital period for the soft X-ray transient sources with orbital periods less than 1 d. By fitting the observed values for eight X-ray transients, we determine an empirical relation that can be used to predict the orbital period of an X-ray transient given only its outburst

  • 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 density contrast and peculiar velocity that can be extended to any order of approximation in the quasilinear regime. We compute the solution up to the fourth order (E4) and establish a

  • Observational Discovery of the Asymptotic Giant Branch Bump in Densely Populated Color-Magnitude Diagrams of Galaxies and Star Clusters
    The huge photometric databases that are being created for stars in the Magellanic Clouds and in Local Group galaxies not only allow a detailed study of the star formation history of these systems but also provide important information on stellar evolutionary theory. Two low-level features above the red clump in the LMC color-magnitude diagram (CMD)

  • Numerical simulation of observations with GOLF on board SOHO
    The main objective of the GOLF Experiment (Global Oscillations at Low Frequencies) on-board the SOHO (Solar and Heliospheric Observatory) space mission is the quantitative knowledge of the internal structure of the Sun by measuring the spectrum of its global oscillations in a wide frequency range (30 nHz to 6 mHz). There is special interest in
