GRAL J024848.7+191331 NOMLI GRAVITATSION LINZALANGAN KVAZARNING FOTOMETRIYASI
"Maqola"
Maqolada Maydanak observatoriyasida 2021-2022 yillar davomida kuzatilgan to‘rt komponentli GRAL J024848.7+191331 nomli gravitatsion linzalangan kvazarning fotometrik tadqiqoti natijalari keltirilgan. Butun sistemaning hamda uning alohida komponentalarining ravshanlik egri chiziqlari ko'rsatilgan. To'rttala komponentning ko'rinma ravshanligi teng darajada o'zgarib turganligi va bu mikrolinzalanishning (hech bo’lmaganda kuchliligi) yo'qligini ko'rsatib o‘tdik. Obektning komponentalari uchta asosiy juftligi o'rtasidagi kechikish vaqtlarining qiymatlarini hisoblab topildi.
