Luminous efficiency based on FRIPON meteors
Esther Drolshagen, Theresa Ott, Detlef Koschny +36
In meteor physics the luminous efficiency is used to convert the meteor's magnitude to the corresponding meteoroid's mass. However, lack of sufficiently accurate verification m…
Dynamical properties of the Molniya satellite constellation: long-term evolution of orbital eccentricity
Elisa Maria Alessi, Alberto Buzzoni, Jerome Daquin +2
The aim of this work is to analyze the orbital evolution of the mean eccentricity given by the Two-Line Elements (TLE) set of the Molniya satellites constellation. The approach is…
Dynamical taxonomy of the coupled solar radiation pressure and oblateness problem and analytical deorbiting configurations
Ioannis Gkolias, Elisa Maria Alessi, Camilla Colombo
Recent works demonstrated that the dynamics caused by the planetary oblateness coupled with the solar radiation pressure can be described through a model based on singly-averaged e…
Science orbits in the Saturn-Enceladus circular restricted three-body problem with oblate primaries
Francisco Salazar, Adham Alkhaja, Elena Fantino +1
This contribution investigates the properties of a category of orbits around Enceladus. In a previous investigation, a set of heteroclinic connections were designed between halo or…
Design and performance of low-energy orbits for the exploration of Enceladus
E. Fantino, F. J. T. Salazar, E. M. Alessi
The icy moons are in the focus of the exploration plans of the leading space agencies because of the indications of water-based life and geological activity observed in a number of…
