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

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

Orion Nebula

introduction1
Introduction
  • Dark nebula are similar to reflection nebula
  • Can only be seen due to the fact that they block out light

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

literature review
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
purpose
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.
