  1. Age of M13 Life of Stars Claudia Piceno Jose Guzman

  2. Overview Why is this an interesting project? What is M13? Observations Life of a Star How we measured the age of our cluster.

  3. M13 Globular Cluster • We calculated the age to be between 12 to 14 billion years old • It is 25,000 light years away from Earth solarius.com/msas/gallery/deepsky/m13_20031004a.html.-19k

  4. Data Nickel Telescope 1-meter located in Mt. Hamilton in San Jose, CA. Filters: B for Blue R for Red V for Green (visual) Three images were taken in each filter: 5 minutes for V and B 3 minutes for R

  5. Red Filter Visual Filter Blue Filter RGB

  6. RBV Combined

  7. The Color Magnitude Diagram of M13 shows: .There is the HB .There is a lot of red giants .That there is a low amount of main sequence stars Bright Faint Blue-Hot Red-Cold

  8. Theory • How do stars form? • How do stars evolve? • Main Sequence to Red Giant to HB. • Using the Star Evolution we figured out the age of our Star Cluster.

  9. Star Formation This is a dust and gas cloud that gravity is collapsing. Gets hot enough for fusion to occur.

  10. Main Sequence

  11. Main Sequence Red Giant

  12. Cluster Evolution Bright Bright Faint Faint Red Blue Blue Red

  13. Conclusions M13 • We used CMD Models to determine the age of M13 Globular Cluster. • Cluster is 12 to 14 billion years old. • Stars are formed by collapsing gas and dust.
