    Abstract Carbon stars constitute a vast and interesting class of chemically peculiar stars which has carbon overabundance relative to oxygen. This class of stars was first identified by Secchi (1868) and is characterized ...
  • BASSALLO DA SILVA, TAYSA (Observatorio NacionalDivisão de Programas de Pós-Graduação - DIPPGBrasilONPrograma de Pós-Graduação em Astronomia, 2017-09-29)
    This work aims at contributing to a more refined ground-based astrometry from the PRAIA code (Platform for the Reduction of Astronomical Images Automatically), more specifically, that of small solar system bodies. Such ...

    Light curves from the occultation of a star by a distant body in the solar system allow us to meausre the dimensions of this latter with kilometric accuracies. This is rivaled only by measurements made by space probes. It ...

    In this work we performed a study about the dynamical stability of co-orbital hypothetical planets (Trojans), around the Lagrangian points $L_{4}$ of known planets which form the compact extrasolar planetary systems Kepler-9 ...

    One way to know the physical properties of Trans-Neptunian objects (TNOs) is the analysis of stellar occultations by these objects. The prediction of a stellar occultation basically depends on comparisons of TNOs' ephemeris ...
  • SAAD OLIVERA, XIMENA BEATRIZ (Observatorio NacionalDivisão de Programas de Pós-Graduação - DIPPGBrasilONPrograma de Pós-Graduação em Astronomia, 2015-07-30)
    Abstract In this work we develop a semi-analytical model to analyze the dynamical evolution of a massive body in coorbital motion with the Moon. We assume that this object was formed together with the Moon and analyze their ...

    Most of our current knowledge of the Solar System relies on ground-based observations involving techniques like photometry and astrometry, but also Lunar Laser Ranging (LLR) and Very Large Baseline Interferometry (VLBI). ...
