Relationship between solar wind corotating interaction regions and the phasing and intensity of Saturn kilometric radiation bursts [PDF]
, 2008 Voyager spacecraft measurements of Saturn kilometric radiation (SKR) identified two features of these radio emissions: that they pulse at a period close to the planetary rotation period, and that the emitted intensity is correlated with the solar wind ...

Characteristics of the Solar Differential Rotation and Activity During Solar Cycle No. 24
UniverseAn analysis of the solar differential rotation (DR) during solar cycle No. 24 (SC24) (2009–2019), based on the Kanzelhöhe Observatory for Solar and Environmental Research (KSO) data set, is presented.

Optical control of solar sails using distributed reflectivity [PDF]
, 2014 The dynamics of solar sails with a variable surface reflectivity distribution are investigated. When changing the reflectivity across the sail film, which can be achieved using electro-chromic coatings, the solar radiation pressure forces and torques ...

Reconnection in a rotation-dominated magnetosphere and its relation to Saturn's auroral dynamics [PDF]
, 2005 The first extended series of observations of Saturn's auroral emissions, undertaken by the Hubble Space Telescope in January 2004 in conjunction with measurements of the upstream solar wind and interplanetary magnetic field (IMF) by the Cassini ...

Symposium - International Astronomical Union, 1997 The rotation of the sun affects the wave propagation in the solar cavity. The measurement of the effect can be used to infer the internal rotation of the sun, and indeed much of what we know today about the dynamics of the solar interior has been derived from observation and interpretation of the rotationally induced splitting of solar p-mode ...

Differential Rotation for Different-sized Sunspot Groups Early Observed by the OGAUC
The Astrophysical Journal, 2023 Solar differential rotation is an important ingredient of the solar dynamo model, not only because the solar rotation profile is one of the key inputs in a solar dynamo model, but also because it imposes constraints for the solar dynamo model.

The Rotation of the Deep Solar Layers [PDF]
The Astrophysical Journal, 2003 From the analysis of low-order GOLF+MDI sectoral modes and LOWL data (l > 3), we derive the solar radial rotation profile assuming no latitudinal dependance in the solar core. These low-order acoustic modes contain the most statistically significant information about rotation of the deepest solar layers and should be least influenced by internal ...

On the Rotation of the Solar Chromosphere [PDF]
The Astrophysical Journal, 2020 Abstract Rotation is a significant characteristic of the Sun and other stars, and it plays an important role in understanding their dynamo actions and magnetic activities. In this study, the rotation of the solar chromospheric activity is investigated from a global point of view with an over 40 yr Mg ii index.

Earth's Rotation and Solar Activity [PDF]
Geophysical Journal International, 1989 Summary The 11-yr signal in the variation of length of day has been successfully identified and significantly linked to solar activity. A physical mechanism involving meteorological and oceanic variation is proposed.
