QQ Boötes: İlk Fotometrik Araştırma

Year 2020, Volume: 1 Issue: 1, 213 - 216, 11.12.2020

Abstract

Literatürde fotometrik çalışması bulunmayan W UMa tipi çift sistemlerin üyesi QQ Boötes'in (QQ Boo, GSC 03483-01409, V=$12^{m}.568$, P=$0^{d}.276478$) gözlemleri Ça-nakkale Ulupınar Gözlemevi'nde bulunan İST60 teleskobuyla yapılmıştır. Gözlemlerde, 60cm ayna çaplı Cassegrain teleskoba bağlı SBIG-STL-1001E CCD kamerası ve Bessell-BVR filtreleri kullanılmıştır. Baş bileşeninin sıcaklığı 5790K bulunmuştur. Üç renk ışık eğrilerinin Wilson-Devinney ile analizinden, sistemin kütle oranı q=2.88 olarak hesaplanmıştır. %22 doluluk oranına sahip, W-alt tipi, lekeli bir sistem olan QQ Boo'nun %11 oranında üçüncü ışık etkisinde olduğu tespit edilmiştir.
