The rotation period of Uranus

Nature, 1986
On 24 January 1986 the spacecraft Voyager 2 transversed the innermost magnetosphere of the planet Uranus, coming as close as 4.2 Uranus radii to the planet. It is pointed out that the magnetic field data provide a direct measure of the rotation period of the planet's interior, where the field is generated. Two period determinations are reported.

Solar Rotation Period Driven Modulations of Plasmaspheric Density and Convective Electric Field in the Inner Magnetosphere

Journal of Geophysical Research: Space Physics, 2019
This paper presents the first analysis of Van Allen Probes measurements of the cold plasma density and electric field in the inner magnetosphere to show that intervals of strong modulation at the solar rotation period occur in the locations of the outer ...

Radio Rotation Period of Jupiter

Science, 1966
The results of observations of Jupiter at 18 megacycles per second indicate that the apparent rotation period drifts cyclically about a constant mean value. The most probable drift period appears to be 11.9 years, Jupiter's orbital period. The mean rotation period during one orbital period is about 0.3 second longer than that of the system III (1957.0)

Jupiter's rotation period

Planetary and Space Science, 1967
Abstract The current belief that Jupiter's rotation period has recently lengthened by 0·8 sec is an error arising from a secular increase of duration of Jovian decametric storms. Periodograms based on the commencement time of decametric storms yield a constant period, 9 h 55 m 29·70 s ± 0·05 s.

Uranus' rotational period

Icarus, 1977
A modified spectroscopic technique was applied to determine the rotational period of Uranus and the orientation of the projected spin axis of the planet. The method consists in obtaining a series of spectra for both a nonrotated planet disk and for a disk rotated 180 degrees.

The Relativistic Quantum Periodically Driven Rotator

Physica Scripta, 2003
Summary: The relativistic periodically driven quantum rotator problem is treated by solving the Dirac equation in the presence of the periodic S-function potential. The relativistic quantum mapping which describes the evolution of the wave function is derived.
