Young Stellar Objects in Dark Nebulae James Haber

Need Help increase knowledge of star formation View parts of the universe previously obscured by dark nebulae Spooky Star Forming Region

Introduction Nebula are clouds of ionized hydrogen gas Large regions of star formation Orion Nebula

Introduction Dark nebula are similar to reflection nebula Can only be seen due to the fact that they block out light Horsehead Nebula

Taurus-Auriga Dark Cloud Literature Review Red and Nebulous Objects in Dark Clouds Search for protostars and T Tauri stars previously missed by Herbig and Rao

Literature Review An optical survey to look for star formation in Lynds Dark Clouds Ratio of Class 0 to Class I protostars was found to be about 1:1, very different from previous 1:10 ratio
