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 ...

The precession of eccentric discs in close binaries [PDF]
, 1999 We consider the precession rates of eccentric discs in close binaries, and compare theoretical predictions with the results of numerical disc simulations and with observed superhump periods.

Search for Axionlike Dark Matter through Nuclear Spin Precession in Electric and Magnetic Fields [PDF]
, 2017 We report on a search for ultra-low-mass axion-like dark matter by analysing the ratio of the spinprecession frequencies of stored ultracold neutrons and 199Hg atoms for an axion-induced oscillating electric dipole moment of the neutron and an axion-wind

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.

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 ...

Detection of significant climatic precession variability in early Pleistocene glacial cycles
Earth and Planetary Science Letters, 2020 Despite having a large influence on summer insolation, climatic precession is thought to account for little variance in early Pleistocene proxies of ice volume and deep-water temperature.

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.

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 ...
