"The Sun's Rotation: Unraveling the Mystery of Long-period Oscillations"

Scientists have discovered a new theory to explain the Sun's differential rotation, which involves long-period oscillations of sound waves in the solar convection zone. These oscillations, detected as swirling motions around the poles, limit the temperature difference between the poles and the equator, ultimately controlling the Sun's bizarre rotation. The relationship between the oscillations and the differential rotation goes both ways, with the oscillations curbing the rotation. This finding could provide insights into the dynamics of other stars as well.

"Sun's Differential Rotation Controlled by Long-Period Oscillations"

Scientists have discovered that long-period high-latitude oscillations in the sun's convection zone play a crucial role in controlling the sun's differential rotation. These oscillations, observed through helioseismology, carry heat from the solar poles to the equator, limiting the temperature difference between the two to less than seven degrees. This small temperature difference influences the sun's global dynamics and is an important feedback mechanism. The study, published in Science Advances, sheds light on the physics of these oscillations and their role in the sun's workings, providing valuable insights for future research.
