For RFS T-tauri stars would fall under stellar evolution, so you are better off knowing about them.

for RFS, are we going to need to know the right ascension + declination of a star?? thnx

I would highly doubt you would have to memorize/ have on your sheet the RA and Dec of the stars/objects. If there is anything with Ra and Dec they would probably give it to you, for example they could hav an ID chart, give you the RA/Dec and then you would have to fill in the rest of the chart. (obviously you would have a star chart on teh event as well)

Does any1 know what right ascension and/or declination is? thnx :D

For state competition do we go into a planetarium and find stars/constellations/deep sky objects?

Right ascension and Declination is the Latitude and Longitude of the celestial sphere. The celestial sphere is pretty much the earth expanded and all the stars are on it on the sphere. There is a celestial equator (0° Declination) which is just the equator of the earth, but expanded onto the celestial sphere. Declination is like the latitude of the sky. It is measured in +/- degrees. All positive degrees are above the celestial equator, and all negative degrees are below. Right ascension is like the longitude of the sky. It is measured in hours and minutes. Possibly in seconds, but I don't think they would go that in-depth. It starts at 0h0m and goes around the celestial sphere until it gets back to 0h0m which would complete 24 hrs, just like in a day. Hope that helped.

It all depends on what state you are in, and who the writer of the event is. Last year ('08) my regionals was an inflatable planetarium, my states was an inflatable planetarium, and nationals was star charts. This year ('09) my regionals was star maps. I don't know what states will be, so I will have to be prepared for both. You should definitely practice with star maps, and try to get at least accustomed to a planetarium. For star maps, one of the most important things- STUDY BAD STAR CHARTS!!! The chance of getting a bad star chart is definitely there, so you gotta be ready for anything.

After we learn the basic neccesities for RFS, like everything that is stated in the rule book, what would you suggest we go more into detail in?
Also, in last year's competition, did you encounter any unusual questions on your test, if so can you state them?

Thank you in advance for responding to those who do!

Really, after you get most of the in-depth knowledge of the stuff in the rule book down there isn't TOO much left to do. Let me get my rule book... I would definintely know like the structure of the sun, I use a picture like this on my info sheet: Image

I would know the evolution of stars very well- all mass levels- everything from a protostar that will become a brown dwarf, to a protostar that will become a supergiant.

Also, know the H-R diagram well, and DEFINITELY know about globular clusters and their H-R diagrams. I have encountered many questions about globular clusters and their H-R diagrams.

As for weird questions I really don't know of any that I can think of. Last year at nationals I was a little surprised by the T Tauri questions but I think I got them :lol:

Hope I could help. :D

Thanks pj o-o I can't spell that whole thing out. I'm sorry.
That picture looks good for my sheet XD But I think I know the structure pretty well. As well as some of the info.
Well I still have some weeks till states. I'll study some more other things like evolution. I can keep getting that confused. :/
We encountered some t tauris in our county test. We missed them all I think XD
