Abstract AR
يمثل هذا البحث ثلاث طيات، أولا : حساب بعض معاملات الإحصاء الوصفي للأقدار الظاهرية و المطلقة و 1لك للنجوم القريبة 1ات التصنيف الطيفي G0V.
ثانيا : تشيد دوال التواتر Ψ (m), Φ (m) للأقدار الظاهرية و المطلقة لهذه النجوم.
ثالثا : إيجاد المسافة r لهذه النجوم على أنها نظاما نجميا يتوزع حول قدر مطلق متوسط في توزيع جاوس.
و قد كانت النتائج مرضية للغاية حيث وصلت النسبة المئوية للخطأ بين r و القيمة المتوسطة حوالي 3%.
Abstract EN
The present paper has three folds: first, to provide some basic descriptive statistical parameters for the apparent and absolute magnitudes of the nearby stars of spectral type GOV stars Second, to establish the frequency functions Q> {M) and ^ {m) of the absolute and apparent magnitudes for these stars.
Third, to compute the distance r of these stars as a system assuming that they scatter around a mean absolute magnitude in a Gaussian distribution.
The accuracy of the numerical results is satisfactoiy in that, the percentage error between r and the mean value is less than 3%.
