| Summary, etc. | In this thesis we presented most of the astrophysical properties of the<br/>three open star clusters; FSR-163, FSR-275, and Majaess 215, using Gaia-<br/>DR3. The membership candidates’ probabilities have been estimated us-<br/>ing pyUPMASK method. Using the clusters’ parallaxes of the members,<br/>we calculated the distance to the clusters, which matched well with our<br/>isochrones fitting results on the color-magnitude diagram. We also deter-<br/>mined the age of the clusters, which agreed well with the results we got<br/>from the 2MASS isochrones. We finally evaluated the following photomet-<br/>ric parameters: the reddening, galactic geometrical distances, luminosity<br/>function, mass function, total masses of the clusters, and the dynamical<br/>relaxation time. Results of FSR-163 and Majaess 215 are published in<br/>[47]. |
| 520 #3 - SUMMARY, ETC. | |
| Summary, etc. | في هذه الرسالة، عرضنا معظم الخصائص الفيزيائية الفلكية لثلاثة حشود نجمية مفتوحه: FSR-163 وFSR-275 وMajaess 215 باستخدام بيانات المنظار الفضائي جايا (الاصدار الثالث).<br/>استخدمنا طريقة pyUPMASK لتحديد احتمالية عضوية النجوم في الحشود. وباستخدام قيم "اختلاف المنظر" للنجوم أعضاء الحشود، قمنا بحساب المسافة إلى هذه الحشود، والتي تطابقت جيدا مع نتائج محاكاة خطوط التوافق النجميه على مخطط اللون-القدر.<br/>كما حددنا عمر الحشود، والذي توافق أيضًا مع النتائج التي حصلنا عليها من خطوط التوافق النجميه لكَتالوج 2MASS. وأخيرًا، عيينا المعاملات الفوتومترية التالية: الاحمرار النجمي، الأبعاد الهندسية المجرية، دالة الكتلة، دالة الإضاءة، والكتلة الكلية، وزمن الاستقرار الديناميكي للحشود . نُشرت النتائج FSR-163 وMajaess 215 في المرجع(Ola Ali et al. 2024, Res. Astr. Astrophys., 24, 125008). |
