  1. Star Formation 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. Star Formation http://coolwiki.ipac.caltech.edu/index.php/Studying_Young_Stars

  5. 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

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

  7. 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

  8. Purpose The purpose of my project is to study star formation in dark nebulae using color-color plots and spectral energy distribution charts to classify and identify young stars.
