Dynamics of two planets in the 3/2 mean-motion resonance: Application to the planetary system of the pulsar PSR B1257+12
(Springer, 2006-04-01)
This paper considers the dynamics of two planets, as the planets B and C of the pulsar PSR B1257+12, near a 3/2 mean-motion resonance. A two-degrees-of-freedom model, in the framework of the general three-body planar ...

Multiple planetary systems: Properties of the current sample
(Elsevier Science, 2017-08)
We carry out analyses on stellar and planetary properties of multiple exoplanetary systems in the currently available sample. With regards to the stars, we study their temperature, distance from the Sun, and metallicity ...
Gravitational effects of Nix and Hydra in the external region of the Pluto-Charon system
(Wiley-Blackwell, 2011-01-01)
Two new companions to the Pluto-Charon binary system have been detected in 2005 by Weaver et al. These small satellites, named Nix and Hydra, are located beyond Charon's orbit. Although they are small when compared to ...

PLANETARY NEBULAE AND THE CHEMICAL EVOLUTION OF THE MAGELLANIC CLOUDS
(UNIV NACIONAL AUTONOMA MEXICO, INST DE ASTRONOMIA, 2009)
The determination of accurate chemical abundances of planetary nebulae (PN) in different galaxies allows us to obtain important constraints on chemical evolution models for these systems. We have a long-term program to ...
Towards an improvement in the spectral description of central stars of planetary nebulae
(EDP Sciences, 2018-02)
Context. There are more than 3000 known Galactic planetary nebulae, but only 492 central stars of Galactic planetary nebulae (CSPN) have known spectral types. It is vital to increase this number in order to have reliable ...
