Differential rotation and chromosphere - CESAR

The DIFFERENTIAL rotation of the Sun and ITS Chromosphere

The Sun is not a solid body, its gaseous composition allows different rotation speeds on its surface, that is, different angular velocities. This is what we call "differential rotation" and it also occur in other gaseous planets such as Jupiter or Saturn. We can use an h-alpha telescope to observe this phenomena and also learn about one of the thinnest and hottest layers of the Sun: the Chromosphere.
