A Note on Celestial Mechanics in Kerr Spacetime

open access: yes, 2014
The Hamilton-Jacobi equation for test particles in the Kerr geometry is separable. Using action-angle variables, we establish several relations between various physical quantities that characterize bound timelike geodesic orbits around a spinning black ...

Kozai Mechanism and real Kozai: Raw Talents of The Highest Order [PDF]

open access: yesarXiv, 2017
A slightly(!!!) philosophical article which looks at some interesting overlaps between some fine mathematical brains and a celestial mechanics legend from Japan.

A MODIFICATION OF GAUSS' METHOD FOR PRELIMINARY DETERMINATION OF A CELESTIAL BODY'S ORBIT

open access: yesOdessa Astronomical Publications, 2016
A modification of classical Gauss’ method for determination of Keplerian elements from the observed positions is considered in this paper. The modification involves the exhaustive enumeration of all possible orbital plane positions in order to improve ...

Principles of the Theory of Vortex Gravitation [PDF]

open access: yesarXiv, 2004
The developed theory proves that a universal vortex motion, along with the pressure variation in a space continuum called ether, is actually the source of the universal gravitation and creation of celestial bodies and their motion in the Universe. Calculations of the gravitation forces are carried out on the basis of the laws of mechanics of continua ...

Numerical integration in celestial mechanics: a case for contact geometry [PDF]

open access: yes, 2019
Several dynamical systems of interest in celestial mechanics can be written in the form of a Newton equation with time-dependent damping, linear in the velocities. For instance, the modified Kepler problem, the spin-orbit model and the Lane-Emden equation all belong to such class. In this work we start an investigation of these models from the point of

A genealogy of fish women and other imagined identities: “The mechanics of fluids” in Larissa Lai's Salt Fish Girl

open access: yesOrbis Litterarum, EarlyView.
Abstract Fluidity invigorates a utopian home in Chinese Canadian author Larissa Lai's Salt Fish Girl (2002). In the novel, the fishlike lesbian couple cyclically returns to their aquatic habitat between mortal reincarnations: from last‐century colonial South China to near‐future bio‐capitalistic Canada, where they recurrently experience displacement ...

Currents in Celestial CFT [PDF]

open access: yes
In this review we discuss currents in celestial CFT and the consistency of their naive symmetry algebras. In particular we study in detail the Jacobi identity and the double residue condition for soft insertions, hard momentum space insertions, and hard celestial insertions. In the latter case we introduce the notion of a "hard current" in CFT and work

Asymptotic velocity for four celestial bodies [PDF]

open access: yes, 2018
Asymptotic velocity is defined as the Ces\`aro limit of velocity. As such, its existence has been proven for bounded interaction potentials. This is known to be wrong in celestial mechanics with four or more bodies. Here we show for a class of pair potentials including the homogeneous ones of degree -a for 0
