PAL 13 SHARSIMON YULDUZ TO‘DASINING FOTOMETRIK TADQIQOTI
##submission.downloads##
Ushbu maqola Palomar 13 sharsimon yulduz to‘dasi Maydanak observatoriyasidagi ko‘p rangli fotometrik kuzatuv ma’lumotlariga
bag‘ishlangan. Obyekt kuz faslining 3 kunlik kuzatuvda 4 xil (B, R, V, I) filtrlarda va 7 xil ekspozitsiya vaqtlarida kuzatilgan. Pal
13 to‘dasining olingan tasvirlarini fotometrik tahlil qilish uchun IRAF dasturi orqali PSF va Apertura fotometrriyasidan
foydalanganmiz. Maydanak observatoriyasining yuqori astronomik iqlimi sharoitida Pal 13 past yuza yorqinligiga qaramay, uning
V,R,I filtrlardagi yulduz kattaliklari va tasvirdagi koordinatalari aniqlandi. Bu fotometrik tadqiqot natijasidan Pal 13ning ylduz
kattaliklari orasidagi bog‘lanishlar olindi. Bu natijalar Gallaktika galosining shakllanish modellarini aniqlashtirsh uchun
ahamiyatga ega.
