Bilim insanlar\u0131, bu y\u00fczy\u0131l bitmeden ya\u015fanacak “nova” patlamas\u0131yla bir y\u0131ld\u0131z\u0131n g\u00f6ky\u00fcz\u00fcn\u00fcn en parla\u011f\u0131 olmaya haz\u0131rland\u0131\u011f\u0131n\u0131 s\u00f6yledi.<\/p>\n

Bu YD’ler beyaz c\u00fccelerin y\u00f6r\u00fcngesindeki normal y\u0131ld\u0131zlardan olu\u015fur.

YD’ler aras\u0131nda bile V Sge a\u015f\u0131r\u0131 bir \u00f6rnek: Bilinen en u\u00e7 YD ve di\u011fer t\u00fcm \u00f6rneklerden 100 kat daha parlak.
