On the equinoctial orbit elements

Celestial Mechanics, 1972
This paper investigates the equinoctial orbit elements for the two-body problem, showing that the associated matrices are free from singularities for zero eccentricities and zero and ninety degree inclinations. The matrix of the partial derivatives of the position and velocity vectors with respect to the orbit elements is given explicitly, together ...

Orbital multiferroicity in pentalayer rhombohedral graphene

Nature, 2023
Orbital multiferroicity reported in pentalayer rhombohedral graphene features ferro-orbital-magnetism and ferro-valleytricity, both of which can be controlled by an electric field.

Study of orbital elements on the neighbourhood of a frozen orbit [PDF]

Journal of Aerospace Engineering, Sciences and Applications, 2008
Frozen orbits are studied, including perturbations due to J5 harmonic and atmospheric drag. Non- singular variables are introduced according to non-singular theory used at INPE Satellite Tracking and Control Center (CRC). Using CBERS-1 (China Brazil Earth Resources Satellite) satellite's data, results are compared with those used nowadays at the INPE ...

The geopotential in nonsingular orbital elements

Celestial Mechanics, 1977
Singularities are eliminated from the geopotential and its partial derivatives for zero eccentricity and inclination, and an expression for the geopotential expansion based entirely on nonsingular orbital elements is developed. The argument relies on the treatments of the geopotential function given by Izsak (1964), Allan (1965) and Kaula (1966); the ...
