Thermophysical Model Development for Hera Mission to Simulate Non-Gravitational Acceleration on Binary Asteroid
Masanori Kanamaru, Tatsuaki Okada, Hiroki Senshu +4
The surface temperature of an asteroid is fundamental information for the design of an exploration mission and the interpretation of scientific observations. In addition, the therm…
Orbit determination methods for interplanetary missions: development and use of the Orbit14 software
Giacomo Lari, Giulia Schettino, Daniele Serra +1
In the last years, a new generation of interplanetary space missions have been designed for the exploration of the solar system. At the same time, radio-science instrumentation has…
Investigation on a Doubly-Averaged Model for the Molniya Satellites Orbits
Tiziana Talu, Elisa Maria Alessi, Giacomo Tommei
The aim of this work is to investigate the lunisolar perturbations affecting the long-term dynamics of a Molniya satellite. Some numerical experiments on the doubly-averaged model,…
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…
Short arc orbit determination and imminent impactors in the Gaia era
F. Spoto, A. Del Vigna, A. Milani +6
Short-arc orbit determination is crucial when an asteroid is first discovered. In these cases usually the observations are so few that the differential correction procedure may not…
Non-resonant secular dynamics of trans-Neptunian objects perturbed by a distant super-Earth
Melaine Saillenfest, Marc Fouchard, Giacomo Tommei +1
We use a secular model to describe the non-resonant dynamics of trans-Neptunian objects in the presence of an external ten-earth-mass perturber. The secular dynamics is analogous t…
Study and application of the resonant secular dynamics beyond Neptune
Melaine Saillenfest, Marc Fouchard, Giacomo Tommei +1
We use a secular representation to describe the long-term dynamics of transneptunian objects in mean-motion resonance with Neptune. The model applied is thoroughly described in Sai…
Long term dynamics beyond Neptune: secular models to study the regular motions
Melaine Saillenfest, Marc Fouchard, Giacomo Tommei +1
Two semi-analytical one-degree-of-freedom secular models are presented for the motion of small bodies beyond Neptune. A special attention is given to trajectories entirely exterior…
