GravDyn: A Python Framework for Gravitational Modeling of Irregular Celestial Bodies Using Polyhedral, mascon, and Series Expansion Methods
Safwan Aljbaae, valerio Carruba, Allan K. de Almeida +4
GravDyn is an open-source Python package for computing gravitational potentials and accelerations around irregular celestial bodies. It implements three approaches within the same…
Analytical modeling of the gravitational potential of irregularly shaped celestial bodies considering three distinct internal structures: application to (21) Lutetia
Marcelo L. Mota, Safwan A., Antonio F. B. A. Prado
The classical polyhedral model is one of the most accurate methods currently used to represent the gravitational field of irregularly shaped bodies. However, it assumes a homogeneo…
Potential series expansion method applied in Analytical Modeling of Gravitational field of Irregularly Shaped Celestial Bodies
Marcelo Lisboa Mota, Safwan Aljbaae, Antonio F. B. A. Prado
This study aims to establish an analytical model that reproduces the gravitational field around non-spherical bodies with constant density. Due to the non-spherical geometry of suc…
Swing-By in Three Dimensions: Closed Form Solutions
Antonio Fernando Bertachini de Almeida Prado
The main goal of the present research is to make a summary of analytical equations that can be found to calculate a swing-by maneuver in the three-dimensional space. Analytical equ…
