In science:

Additionally, if the stellar mass-to-light ratio of UGC 12695 is increased to 1.7, a reasonable value for both HSB and LSB galaxies, there is no need to invoke any dark matter to explain the maximum observed rotational velocity at the last measured point of UGC 12695’s rotation curve.
Star Formation and Tidal Encounters with the Low Surface Brightness Galaxy UGC 12695 and Companions
On the other hand, it is quite likely that there is significant dark matter outside the observed radius (else the rotation curve would show some turn over), and thus we are merely viewing a lower limit of the galaxy’s rotational velocity.
Star Formation and Tidal Encounters with the Low Surface Brightness Galaxy UGC 12695 and Companions
From the rotation curve of UGC 12695 it is apparent that its near solid body rotation makes determining κ relatively easy.

Physics of Grain Alignment

However, the baroclinic instability may have time to operate within the differentially rotating burning layer, potentially bringing it into rigid rotation.
Rotational Evolution During Type I X-Ray Bursts
This remains true as the atmosphere expands, since a rigidly rotating spherical shell stays rigidly rotating as it expands outwards (because the fractional change in the distance from the rotation axis is the same for all latitudes).
Rotational Evolution During Type I X-Ray Bursts
Thus to observe a single, coherent frequency requires either the atmosphere to be rigidly rotating, or the burning region to be vertically thin (Miller 2000), so the differential rotation across it is small.
