الدورات النشطة (Info)
توزيع المواضع النجمية عبر سطح نجمي يختلف كالحالة الشمسية، ولكنه يختلف عن أنواع مختلفة من النجوم، هذا يتوقف على ما إذا كان النجم ثنائيا أم لا. نفس نوع الدورات النشاط التي تم العثور عليها للشمس يمكن أن يتم رؤيتها من قبل النجوم الأخرى، مطابقا للنظام الشمسي (2 مرات) 11دورة في السنة. بعض النجوم ليس لديها دورات أطول، وربما مماثلة للحدود الدنيا للشمس.
