Mercury’s resonant rotation from secular orbital elements [PDF]

open access: yes, 2015
We used recently produced Solar System ephemerides, which incorporate 2 years of ranging observations to the MESSENGER spacecraft, to extract the secular orbital elements for Mercury and associated uncertainties.

Observations of the Rigollet Comet from Korea and Japan [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2014
Since Rigollet first discovered a comet in 1939, many follow-up observations have been made, particularly in Europe. It is now known that the Rigollet comet is identical with the one observed by Herschel in 1788, and thus it is now called 35P/1939 O1 ...

Correlations of Orbital Elements for Visual Double Stars [PDF]

open access: yesSerbian Astronomical Journal, 2010
In this paper, the authors examine the dependence of correlation coefficients of orbital elements on the length of the orbital arc covered by measurements, on measurements of different accuracies, and on the number of measurements.

Precise orbital elements, masses and parallax of the spectroscopic–interferometric binary HD 26441 [PDF]

open access: yes, 2017
The orbit of the visual-speckle binary A 2801 (HD 26441) was calculated independently of the previously published double-lined spectroscopic solution, obtaining similar values for the common orbital elements.

First-principles theory of intrinsic spin and orbital Hall and Nernst effects in metallic monoatomic crystals [PDF]

open access: yesPHYSICAL REVIEW MATERIALS, 2022
The generation of spin and orbital currents is of crucial importance in the field of spin-orbitronics. In this work, using relativistic density functional theory and the Kubo linear-response formalism, we systematically investigate the spin Hall and ...

Osculating Keplerian Elements for Highly Non-Keplerian Orbits [PDF]

open access: yes, 2017
This paper presents a mapping between the elements of highly non-Keplerian orbits and classical orbital elements. Three sets of elements are discussed and mappings are derived in closed, analytical form for both the direct and inverse problem. Advantages

Approximations for Secular Variation Maxima of Classical Orbital Elements under Low Thrust

open access: yesMathematics, 2023
The reachability assessment of low-thrust spacecraft is of great significance for orbital transfer, because it can give a priori criteria for the challenging low-thrust trajectory design and optimization.

Calculation Mars – Earth distance and Mars orbital elements with Julian date

open access: yesIraqi Journal of Physics, 2023
In this paper, the Mars orbital elements were calculated. These orbital elements—the major axis, the inclination (i), the longitude of the ascending node (W), the argument of the perigee (w), and the eccentricity (e)—are essential to knowing the size ...
