Looking for anti-solar differentially rotating stars utilizing the Rossby quantity. An software to the Kepler area

Opposite to photo voltaic rotation, antisolar rotation is characterised by gradual equatorial rotation and quick polar rotation. Such a rotation profile has been discovered for many years in numerical simulations for top Rossby numbers however has by no means been unambiguously noticed for cool solar-type stars on the primary sequence. The authors have devised a theoretical formulation to estimate fluid Rossby numbers from the efficient temperature and the rotational interval. The authors utilized their strategy and obtained a promising candidate, KIC 10907436, which most likely has antisolar differential rotation. The developed technique could be utilized to Kepler or future PLATO missions, places constraints on the hyperlink between rotation and magnetism, and deepens our understanding of dynamo concept and magnetic exercise in the long term.
