Minimum period Pmin versus absolute differential rotation dΩ. The colors represent different temperature bins, the dotted black lines mark our detection limits. The dashed blue area shows theoretical predictions from Küker & Rüdiger (2011). We found that dΩ is almost independent of rotation period over a wide period range, but slightly increases towards short periods. Stars hotter than 6700 K do not follow the overall trend. The black lines show linear fits to our measurements, discarding stars hotter than 6700 K (dash-dotted line) and using all data points (dashed line), respectively.
