I did quite well with Reach for the Stars for state... but because our high school team needed more people, me being a freshman, I got transferred to that one from my middle school team (where I'm from, my district is bringing both the Div. B and C teams to nationals). I will now work on this for nationals. Seems very different. I'll need WAY more notes, and memorizing constellations and stars doesn't seem to be what this is all about.

You could be asked about constellations for DSOs and other such questions, but otherwise, you're right. The focus is indeed different (as far as I can tell - I never competed in Reach for the Stars, as I've only been in div C). Good luck at nationals!
Anyone have any practice questions at all? Besides those on the Scio national website. Just worried I'm missing info. I have images of all the DSO's, solid info on them. But I feel like there;s so much more.
If you go to the Test Exchange, under Tufts Wright Center, you should find the national tests from when stellar evolution was last a topic.

Here is a link to a thread that contains some good information on the event. I suggest you read through it to get a better idea on the topics and types of questions.

Hmmm I have a question.

Say you know a galaxy has a hydrogen line at 656 nm. The redshifted line is now at 1115 nm. What would be the redshift value and how fast would the galaxy be going. Also, how far is the galaxy away from us? (H= 70)

Check my work please :)

So you can find redshift by using (observed - emitted)/emitted = (1115-656)/656 = 459/656 = .7 This is the redshift value.
Now you can use v= zc = .7 * 300000 km/s = 210000 km/s. This is how fast the galaxy is moving away from us.
Then you can use Hubble's Law for distance. D = V/H = (210000 km/s)/(70 km/s/Mpc) = about 3000 Mpc.

Did I do it right? Any response would be helpful :D

I feel like this may have been asked before, but do you guys use laptops or binders? And whichever you use, do you have your partner have the same stuff in each or do you each keep different stuff and split the test?

Thanks!

We do two laptops, with the same info on each. Typically we'll split the test, and then go over it together at the end.

We only had one binder at regionals, but we'll get either another binder or a laptop for states.

From invitationals to states we used one binder and one laptop. The binder we put in really quick info on DSOs, formulas, diagrams. The laptop we had a lot of extra information. It worked out pretty well for us, but it really just depends what is easiest to sort through (for me it was the binder, my partner wanted the laptop).
