SHARSIMON YULDUZ TO‘DALARINING KOSMIK KUZATUV MA'LUMOTLARI TAHLILI
##submission.downloads##
Biz GAIA DR2 kosmik dasturi doirasida olingan va de Boer et al. (2019) ishida nashr etilgan 81 ta sharsimon yulduz
to’dalari (ShYT)ning ko'rinma sirt zichligi bo'yicha kuzatuv ma'lumotlarini tahlil qildik. Biz birinchi navbatda GAIA DR2
kuzatuv ma'lumotlarining sifatini HST tomonidan olingan shunga o'xshash ma'lumotlar bilan taqqoslab o'rgandik. Ilgari HST
kosmik kuzatuv ma'lumotlari misolida sinovdan o'tgan 3 parametrli modelimizdan foydalanib, biz konsentratsiya
parametrining to’da markazigacha bo'lgan qiymatlarini topdik. Buning uchun birinchi navbatda GAIA ma’lumotlarini to'rt
guruhga bo'lish va ularning sifatini bir qator jismoniy jihatlardan solishtirish kerak edi. Biz topilgan ShYT larning
kontsentratsiya parametrining ushbu ob'ektlarning asosiy xususiyatlariga bog'liqligini tekshirdik. Olingan natijalar klaster
markaziga yulduz kontsentratsiyasi darajasi bo'yicha GK larning oldingi tasnifining to'g'riligini tasdiqlaydi.
