Re: Astronomy C
Can anyone explain Of stars? I've seen references to them in papers about WR and LBV stars but when I search for them I can't find much.

Here. I'm not certain, but the spectral features sound to me like they would be indicative of being slightly more evolved than an O-type main sequence star.orangewhale wrote:Can anyone explain Of stars?

Re: Astronomy C
How do y'all prepare notes for this event?
Columbia University. Maybe starting an invitational. No promises.

Re: Astronomy C
Start off with Wikipedia and get the general concepts down, along with specific details for the general information. After, if you can get yourself a copy of Carroll and Ostlie, it usually does wonders. For DSOs, start off with Wikipedia and then gradually move onto research papers. It's useful to have a lot of images of each of the DSOs as well. For math, I just have one big formula sheet of stuff I've found over the years.alchzh wrote:How do y'all prepare notes for this event?

Re: Astronomy C
Hi, I need to know how you guys get information on DSOs because I can't get some information for some of the objects. Please do let me know ASAP if there is a database which I can access because even Wikipedia and NASA don't have all of the information. Thank you in advance!

Any laptop is allowed with no WiFi. Must have at most a total of 2 binders and laptops (i.e. 1 laptop 1 binder, 2 laptops, etc). You can bring whatever information you want.ashucha wrote:Also, what resources like computers and sheets are we allowed to bring for the tests and how many for each team of two?

Re: Astronomy C
First of all, thank you. I used Chandra and some research papers but they still could not give me more information than NASA and Wikipedia. I would really appreciate it if you could tell me which research papers you used.

Re: Astronomy C
Generally, searching the DSO on arxiv is enough to get a decent amount of information. There is a limit to the amount of information an ES will dare ask on a test, so you don't need every last little detail.ashucha wrote:First of all, thank you.

Re: Astronomy C
Another good resource is SIMBAD; It usually has almost all the numbers I need for a DSO. Arxiv is better for very specific things and if you're good at reading these kinds of documents. Chandra is the most user-friendly probably. AAVSO is also a nice website to find light curves of variable stars on; I've found that many tests-makers use it. All of these sites should have all the information you will ever need for the DSOs, but even more research on your own time can never hurt.antoine_ego wrote:Generally, searching the DSO on arxiv is enough to get a decent amount of information.
