Euler, Jacobi, and Missions to Comets and Asteroids [PDF]

, 2001
Whenever a freely spinning body is found in a complex rotational state, this means that either the body is a recent victim of an impact or a tidal interaction, or is a fragment of a recently disrupted progenitor.

Nonlinear Effects on the Precessional Instability in Magnetized Turbulence

Atmosphere, 2019
By means of direct numerical simulations (DNS), we study the impact of an imposed uniform magnetic field on precessing magnetohydrodynamic homogeneous turbulence with a unit magnetic Prandtl number.

Gravitational radiation from precessing accretion disks in gamma-ray bursts [PDF]

, 2010
We study the precession of accretion disks in the context of gamma-ray burst inner engines. Our aim is to quantitatively estimate the characteristics of gravitational waves produced by the precession of the transient accretion disk in gamma-ray bursts ...

Quasiperiodic spin-orbit motion and spin tunes in storage rings [PDF]

, 2004
We present an in-depth analysis of the concept of spin precession frequency for integrable orbital motion in storage rings. Spin motion on the periodic closed orbit of a storage ring can be analyzed in terms of the Floquet theorem for equations of motion

Null and Timelike Geodesics near the Throats of Phantom Scalar Field Wormholes

Universe, 2020
We study geodesic motion near the throats of asymptotically flat, static, spherically symmetric traversable wormholes supported by a self-gravitating minimally coupled phantom scalar field with an arbitrary self-interaction potential.

The Impact of Orbital Precession on Air‐Sea CO2 Exchange in the Southern Ocean

Geophysical Research Letters, 2023
Orbital precession has been linked to glacial cycles and the atmospheric carbon dioxide (CO2) concentration, yet the direct impact of precession on the carbon cycle is not well understood.

Gyroscope deviation from geodesic motion: quasiresonant oscillations on a circular orbit [PDF]

, 2003
General relativistic spin-orbit interaction leads to the quasiresonant oscillation of the gyroscope mass center along the orbital normal. The beating amplitude does not include the speed of light and equals the ratio of the intrinsic momentum of the ...

Triadic resonances in nonlinear simulations of a fluid flow in a precessing cylinder

New Journal of Physics, 2015
We present results from three-dimensional nonlinear hydrodynamic simulations of a precession driven flow in cylindrical geometry. The simulations are motivated by a dynamo experiment currently under development at Helmholtz-Zentrum Dresden-Rossendorf in ...

Magnetic resonance signal [PDF]

Tehnika, 2019
The aim of this paper is to describe the magnetic resonance signal, how it occurs, what types of the signal there are and what they are used for. In order to achieve that goal, the original article of Isidor Isaak Raby was given, which disclosed the ...
