Solar sail orbits at artificial Sun-Earth libration points [PDF]

, 2005
In this Note a new family of solar sail orbits will be investigated in the sun-Earth circular restricted three-body problem. It will be shown that periodic orbits can be developed that are displaced above or below the plane of the restricted three-body ...

A unified framework for the orbital structure of bars and triaxial ellipsoids [PDF]

, 2015
We examine a large random sample of orbits in two self-consistent simulations of N-body bars. Orbits in these bars are classified both visually and with a new automated orbit classification method based on frequency analysis.

Checking the possibility of determining the relative orbits of stars rotating around the center body of the Galaxy

Open Astronomy, 2022
The results of observations of selected stars orbiting the central body of our Galaxy, which, according to the latest data, has a mass of about 4 million of solar mass, are considered.

The dynamical environment of the primary in the triple asteroid (45) Eugenia

Open Astronomy, 2020
We investigated the dynamical behavior in the potential of the primary in the triple asteroid (45) Eugenia with the calculation of the full gravitational potential caused by its 3D irregular shape.

Satellite Requirements for Observation of Close Proximity Celestial Bodies

Engineering Proceedings, 2022
Celestial bodies of our solar system remain as a major unexplored and unexploited reserve of natural resources available to humans. Furthermore, those constitute a valuable source of information about the origins and evolution of the solar system and an ...

Optimization of ferroelectricity and endurance of hafnium zirconium oxide thin films by controlling element inhomogeneity

Journal of Advanced Ceramics
Ferroelectric thin films based on HfO2 have garnered increasing attention worldwide, primarily due to their remarkable compatibility with silicon and scalability, in contrast to traditional perovskite-structured ferroelectric materials.
