• openAccess   An improved algorithm to develop semi-analytical planetary theories using Sundman generalized variables 

      López Ortí, José Antonio; Agost Gómez, Vicente; Barreda Rochera, Miguel Elsevier (2015-02)
      One of the main problems in celestial mechanics is the construction of analytical theories of planetary motion. The most common solution of this problem is arranged by means of Poisson series developments. These developments ...
    • closedAccess   Computational tools to construct semi-analytical planetary theories 

      López Ortí, José Antonio; Martínez Usó, María José; Marco Castillo, Francisco José Taylor & Francis (2008)
      The main aim of this paper is the construction of a set of computational tools in order to improve the management of large expansions used in celestial mechanics. This package involves an iterative algorithm to develop the ...
