  • ANTUNES MARQUES, GABRIELA (Observatorio NacionalDivisão de Programas de Pós-Graduação - DIPPGBrasilONPrograma de Pós-Graduação em Astronomia, 2019-07-17)
    The photons propagating in the Universe have their trajectories disturbed due to the presence of massive structures along the line-of-sight, producing the so-called gravitational lensing effect. Because it is sensitive to ...
  • BATISTA SOUZA, TIAGO (Observatorio NacionalDivisão de Programas de Pós-Graduação - DIPPGBrasilONPrograma de Pós-Graduação em Astronomia, 2015-11-04)
    Massive stars are very complex objects and up to now their evolution is not well understood yet. Among the massive stars, the Classical Be stars are the subject of this dissertation. They are B-type, non-supergiants stars, ...
  • CACERES REATEGUI, JESSICA GIOVANNA (Observatorio NacionalDivisão de Programas de Pós-Graduação - DIPPGBrasilONPrograma de Pós-Graduação em Astronomia, 2015-09-29)
    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 ...
  • LEMOS PORCIUNCULA ALVES, THAIS (Observatorio NacionalDivisão de Programas de Pós-Graduação - DIPPGBrasilONPrograma de Pós-Graduação em Astronomia, 2020-08-13)
    he baryonic acoustic oscillations (BAO) are a consequence of the competition between the photons radiation pressure and the gravitational force of the dark matter over the photon-baryon fluid. This phenomenon results in a ...
  • LOPES DE OLIVEIRA, NICOLAS OTAVIO (Observatorio NacionalDivisão de Programas de Pós-Graduação - DIPPGBrasilONPrograma de Pós-Graduação em Astronomia, 2020-03-13)
    The intracluster light (ICL) is defined as a low surface brightness component of galaxy clusters made up of stars that do not belong to any specific galaxy, but are linked to the system’s gravitational potential. Although ...
  • MOURA LOPES, ERIC (Observatorio NacionalDivisão de Programas de Pós-Graduação - DIPPGBrasilONPrograma de Pós-Graduação em Astronomia, 2021-03-30)
    The metal-poor stars composition is an important diagnosis in the matter of galactic chemical evolution. The peculiar abundance of carbon, nitrogen, and oxygen in cold stars reveal details about the first generations of ...
