Güney Yarımküre'den V4396 Sgr ve BK Ind Ayrık Çift Yıldızlarının Tayfsal Gözlemleri

Year 2020, Volume: 1 Issue: 2, 689 - 691, 11.12.2020

Abstract

Bu çalışmada Güney Yarımküre gökyüzünden seçilen V4396 Sgr ve BK Ind ayrık çift yıldızlarının, Güney Afrika Astronomi Gözlemevi'nde elde edilen, ilk tayfsal gözlem verileri sunulmuştur. V4396 Sgr ve BK Ind ayrık çift yıldızlarının bileşenlerinin dikine hız eğrileri çapraz-eşleme (cross-correlation function) ve KOREL yöntemleri kullanılarak elde edilmiştir. Seçilen ayrık çift yıldızların tayfsal kütle oranları sırasıyla 0.88$\pm$0.03 ve 0.86$\pm$0.05 olarak belirlenmiş ve yörünge parametreleri hesaplanmıştır.
