1 Young Stellar Objects in Dark Nebulae James Haber

2 Need Help increase knowledge of star formation View parts of the universe previously obscured by dark nebulae Spooky Star Forming Region http://apod.nasa.gov/apod/ap041101.html

3 Introduction Nebula are clouds of ionized hydrogen gas Large regions of star formation Orion Nebula http://apod.nasa.gov/apod/ap060119.html

4 Introduction Dark nebula are similar to reflection nebula Can only be seen due to the fact that they block out light Horsehead Nebula http://apod.nasa.gov/apod/ap030713.html

5 Taurus-Auriga Dark Cloud http://www.usm.uni-muenchen.de/ys/iras_images.html Literature Review Red and Nebulous Objects in Dark Clouds Search for protostars and T Tauri stars previously missed by Herbig and Rao

6 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
