Differential rotation - Wikipedia
WEBDifferential rotation affects stellar optical absorption-line spectra through line broadening caused by lines being differently Doppler-shifted across the stellar surface. Solar differential rotation causes shear at the so-called tachocline.
Differential Rotation | COSMOS - Swinburne
WEBDifferential Rotation. In a rotating solid body, regions that are adjacent at one point in time will remain adjacent as the body rotates. This means that points further from the rotation centre will travel at greater speeds than those closer in.
Lesson: Differential Rotation of the Sun - Solar and Heliospheric ...
WEBHowever, unlike Earth which rotates at all latitudes every 24 hours, the Sun rotates every 25 days at the equator and takes progressively longer to rotate at higher latitudes, up to 35 days at the poles. This is known as differential rotation. The Sun rotates in the same direction as Earth.
Solar Rotation Varies by Latitude - NASA
WEBJan 23, 2013 · In fact, the Sun’s equatorial regions rotate faster (taking only about 24 days) than the polar regions (which rotate once in more than 30 days). The source of this “differential rotation” is an area of current research in solar astronomy. The Sun rotates on its axis once in about 27 days.
Rotation of the Sun - Windows to the Universe
WEBAug 16, 2005 · Differential rotation is apparently the main driver of the 11-year sunspot cycle and the associated 22-year solar cycle. The notion that differential rotation and convective motion drive these cycles was first put forth in 1961 by the American astronomer Horace Babcock, and is now known as the Babcock Model.

The Sun’s differential rotation is controlled by high-latitude
WEBMar 27, 2024 · The differential rotation profile in a statistically stationary state is determined by a balance between the Coriolis force and the latitudinal pressure gradient force, which leads to the equation for thermal wind balance (eq. S4).
Differential Rotation - Vocab, Definition, and Must Know Facts
WEBDifferential rotation impacts the stability and evolution of accretion disks by redistributing angular momentum within the disk. The varying speeds at different radial positions lead to shear forces that can enhance turbulence and mixing within the disk.
Solar differential rotation reproduced with high-resolution
WEBSep 13, 2021 · In this study, we reproduce the solar-like differential rotation in a high-resolution calculation with solar parameters, such as the stratification, the luminosity and the rotation rate.
The differential rotation of stars - IOPscience
WEBMay 31, 2005 · The theoretical predictions on the differential rotation of the stars agree with observations. A brief discussion is held here on the relation between the magnetic activity of stars and the nonuniformity of their rotation and on prospects for further development of the theory.
