Abstract AR
تم حساب و رسم عامل المعدنية [Fe/H] لعدد من النجوم مرتبطة بها كواكب خارجية (Extra-solar planets) كدالة لكتلة النجوم (M*).
النتائج بينت أن هنالك علاقة خطية بين كتلة نجوم تلك الكواكب و عامل معدنيتها.
هذه العلاقة يمكن أن تعطى بالصيغة : Y=0.0045X+0.065. إن حدود المعدنية وجدت في حدود المديات (0,18 إلى 0,3) نسبة إلى حدود الكتلة ضمن المدى (0,76 إلى 1,44) من كتلة الشمس.
Abstract EN
The metallicity [Fe / H] for several stars accompanied by Extra-solar planets were calculated and plotted as a function of stars mass (M*).
Results showed that masses of Extra-solar planets stars are well correlated with their metallicity .This relation could be explained by the equation : Y = -0.0045x + 0.065.
The metallicity limit is found to be in the range of (0.18 to 0.3), relative to the mass limit in the range of (0.76 to 1.44) MSun.
This criteria is a good tool that can be used by observers who are aiming for detecting Extra-solar planets.
