1 Star Formation in Dark Nebulae
James Haber

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

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

4 Star Formation

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

6 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 Taurus-Auriga Dark Cloud

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.

11 What is the problem? Knowledge Base Lit Review(Check this) This
Does this answer What is the hypothesis Dependent variable Up or down? Which? Why? How do we know? Method Does the method Actually test the hypothesis?
