The Sun rotates on its axis
Multiple observational and historical studies confirm that the Sun rotates on its axis, exhibiting differential rotation across various latitudes and layers.
The claim is a specific, well-established empirical fact about the Sun. Several retrieved papers (such as [2], [6], and [9]) explicitly discuss solar rotation rates, axes, and historical determinations of solar rotation, overwhelmingly supporting the claim without any refuting evidence.
