Overview
Why is this an interesting project?What is M13?ObservationsLife of a StarHow we measured the age of our cluster.

We calculated the age to be between 12 to 14 billion years old
It is 25,000 light years away from Earth

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

The Color MagnitudeDiagram of M13 shows:
.There is the HB
.There is a lot of red giants
.That there is a low
amount of main sequence stars

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.

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

Conclusions 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.
