The free precession and libration of Mercury [PDF]

open access: yesIcarus, 2005
An analysis based on the direct torque equations including tidal dissipation and a viscous core-mantle coupling is used to determine the damping time scales of O(10^5) years for free precession of the spin about the Cassini state and free libration in longitude for Mercury.

Obliquity of Mercury: Influence of the precession of the pericenter and of tides [PDF]

open access: yesIcarus, 2017
Mercury is expected to deviate from the classical Cassini state since this state is defined for a uniformly precessing rigid planet. We develop an extended Cassini state model that includes the variations (or nutations) in obliquity and deviation induced by the slow precession of the pericenter.

Angular Precession of Elliptic Orbits. Mercury ()

open access: yesInternational Journal of Astronomy and Astrophysics, 2012
The relativistic precession of Mercury -43.1 seconds of arc per century, is the result of a secular addition of 5.02×10-7 rad. at the end of every orbit around the Sun. The question that arises in this paper, is to analyse the angular precession at each single point of the elliptic orbit and determine its magnitude and oscillation around the mean value,

Instantaneous Relativistic Precession of Mercury ()

open access: yesJournal of Modern Physics
The extra precession of Mercury - 42.9 seconds of arc per century - explained by General Relativity (GR), is the result of a secular addition of 5.02 × 10−7 rad. at the end of every orbit around the Sun. We will analyze, the instantaneous precession and its addition along one orbit, determine the magnitude and oscillations around ...

Might the 2PN Perihelion Precession of Mercury Become Measurable in the Next Future?

open access: yesUniverse, 2023
The Hermean average perihelion rate ω˙2PN, calculated to the second post-Newtonian (2PN) order with the Gauss perturbing equations and the osculating Keplerian orbital elements, ranges from −18 to −4 microarcseconds per century μascty−1, depending on the

Frame-Dragging in Extrasolar Circumbinary Planetary Systems

open access: yesUniverse, 2022
Extrasolar circumbinary planets are so called because they orbit two stars instead of just one; to date, an increasing number of such planets have been discovered with a variety of techniques.

About the theory of relativity

open access: yesЛитьë и металлургия, 2023
It is shown that the Earth, the Sun and the stars are not inertial systems. The speed of movement of one inertial system relative to another does not affect the parameters of the moving system.

Constraints on long range force from perihelion precession of planets in a gauged $$L_e-L_{\mu ,\tau }$$ L e - L μ , τ scenario

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
The standard model leptons can be gauged in an anomaly free way by three possible gauge symmetries namely $${L_e-L_\mu }$$ L e - L μ , $${L_e-L_\tau }$$ L e - L τ , and $${L_\mu -L_\tau }$$ L μ - L τ .
