PHYS 1412: Lab 29

I haven't thought about the exam next week yet. On the sunny side, I did Lab 29 earlier this evening (yesterday, actually) and the CD reading and also the Internet Assignment for the week after next. Some of the IA was from an IA last semester. So, other than the exam, I have this and next week off. However, I should do the Chapter 18 questions (finished reading it a day or two ago) and really get in good stead. I have an BritLit paper to write and some special work projects pending so I won't get too excited yet. :)

Conclusion for Lab 29
"Globular clusters can contain millions of stars and are very large. Open clusters are much smaller and may have hundreds of stars at best. The shape of a globular cluster is mostly spherical with the densest concentration of stars in the center. The stars within a globular cluster are older than those in open clusters, as determined by their composition: mostly hydrogen and helium with none of the heavier elements of young stars. The stars in globular clusters also tend to be in the lower mass (and longer-lived) G, K, and M classes and thus their colours are yellow, orange, and red. Open clusters have higher mass stars that tend to be bright blue."
