النجوم السابقة (Info)
في أنظمة النجوم الثنائية القريبة، يمكن أن تفقد إحدى النجوم كتلة لصالح مرافقه الأثقل. نجوم نابضة والتي تعمل بالطاقة المتراكمة قد تؤدي إلى فقد الكتلة. يمكن للنجم المتقلص أن يصبح كائنا كوكبيا. مثال على ذلك كوكب المشتري الذي يدور حول النجم النابض PSR J1719-1438. قد تصبح هذه الأقزام البيضاء المنكمشة كوكب هيليوم أو كوكب كربون.
