Abstract

Bu
çalışmada, DEFPOS tayfölçeri kullanılarak galaksimizdeki on farklı iyonize
olmuş hidrojen kaynağından (Sh2-108, Sh2-119, Sh2-136, Sh2-206, Sh2-228, IC5146,
IC444, NGC6572, NGC6960 ve NGC7380) elde edilen Ha tayf sonuçlarını vermekteyiz. Ha tayfları yıldızlararası ortamdaki iyonize gazın bazı
fiziksel durumları (parlaklıkları, LSR’a göre hızları ve çizgi genişlikleri
gibi) hakkında detaylı bilgi sağlamaktadır.   Bu
tayflardan, yapıların LSR’a göre hızları ve parlaklıkları sırasıyla, Sh2-108
için 28.16 km/s ve 160.48 R, Sh2-119 için 14.40 km/s ve 214.22 R, Sh2-136 için
-20.08 km/s ve 458.63 R, Sh2-206 için -2.82 km/s ve 173.29 R, Sh2-228 için
20.21 km/s ve 163.64 R, IC5146 için -7.87 km/s ve 103.56 R, IC444 için -11.50
km/s ve 318.47, NGC6572 için -13.94 km/s ve 114.51 R, NGC6960 için -5.68 km/s
ve 70.40 R NGC7380 için -47.48 km/s ve 524.271 R olarak bulunmuştur. DEFPOS
tayfölçerinin yayılı iyonize gazın çalışılması için güçlü bir alet olduğuna ve
bu yeni sonuçların literatüre katkı sağlayabileceğine inanmaktayız.
