## # Describe each phase of the evolution for each star 1.) Using a solar-metallic

Describe each phase of the evolution for each star
1.) Using a solar-metallicity star (1.27 solar masses), describe each phase of the evolution the star goes through with a time scale. Use an HR diagram, a Kipenhahn diagram and a log pc, log Tc graph to help with visuals.
2.) With a solar-metallicity star (6.5 solar masses), describe each phase of the evolution the star goes through with a time scale and compare it with the previous star. Use an HR diagram, a Kipenhahn diagram and a log pc, log Tc graph to help with visuals. (Different diagrams from the previous hence why a different mass.)
3.) Calculate the evolution of the same star (from problem 2), but with [Fe/H] = −1. Compare the [Fe/H] = 0 and −1 evolutionary tracks for this star in an H-R diagram and log Tcvs log ρc. What are the main differences?
4.) Finally with a solar-metallicity star (55 solar masses), describe each phase of the evolution the star goes through with a time scale. Use an HR diagram, a Kipenhahn diagram and a log pc, log Tc graph to help with visuals. Explain the different evolutionary phases and how it is different from the others.
5.) Conclusion.

## Your term assignment is to participate in a citizen science astronomy experiment

Your term assignment is to participate in a citizen science astronomy experiment on zooniverse.org. You’ll work with real, cutting edge data from one of the world’s leading observatories to study some fascinating astrophysics. This will involve helping the scientists to analyze data by looking for interesting objects and patterns in that data. You’ll be expected to keep a good record of your work, and write a report on the science that you’re helping with.
Here is the link to the Zooniverse Experiment i chose:

IF YOU DONT WANT TO CREATE AN ACCOUNT I CAN GIVE YOU MINE.
