A generalization of the equinoctial orbital elements [PDF]
Celestial Mechanics and Dynamical Astronomy, 2021 We introduce six quantities that generalize the equinoctial orbital elements when some or all the perturbing forces that act on the propagated body are derived from a disturbing potential. Three of the elements define a non-osculating ellipse on the orbital plane, other two fix the orientation of the equinoctial reference frame, and the last allows one

Mercury's resonant rotation from secular orbital elements [PDF]
, 2015 We used recently produced Solar System ephemerides, which incorporate two years of ranging observations to the MESSENGER spacecraft, to extract the secular orbital elements for Mercury and associated uncertainties.

Orbital Parameter Determination for Wide Stellar Binary Systems in the Age of Gaia [PDF]
, 2020 The orbits of binary stars and planets, particularly eccentricities and inclinations, encode the angular momentum within these systems. Within stellar multiple systems, the magnitude and (mis)alignment of angular momentum vectors among stars, disks, and planets probes the complex dynamical processes guiding their formation and evolution.

Constraining the orbits of sub-stellar companions imaged over short orbital arcs [PDF]
, 2015 Imaging a star's companion at multiple epochs over a short orbital arc provides only four of the six coordinates required for a unique orbital solution. Probability distributions of possible solutions are commonly generated by Monte Carlo (MCMC) analysis, but these are biased by priors and may not probe the full parameter space.

Higher orbital integrals, Shalika germs, and the Hochschild homology of Hecke algebras [PDF]
arXiv, 2000 We give a detailed calculation of the Hochschild and cyclic homology of the algebra $\CIc(G)$ of locally constant, compactly supported functions on a reductive p-adic group G. We use these calculations to extend to arbitrary elements the definition the higher orbital integrals introduced in \cite{Blanc-Brylinski} for regular semisimple elements.

Canonical elements for collision orbits [PDF]
Celestial Mechanics and Dynamical Astronomy, 2000 I derive a set of canonical elements that are useful for collision orbits (perihelion distance approaching zero at fixed semimajor axis). The coordinates are the mean anomaly and the two spherical polar angles at aphelion.

An Improvement of the Orbital Elements of Hyperion [PDF]
Symposium - International Astronomical Union, 1979 For the improvement of the orbital elements of Hyperion, a program of photographic observations of Saturnian satellites has been made since the opposition of 1966. In this paper are presented the reduction method and results derived from the observations during the oppositions of 1968 and 1977.
