### Re: Astronomy C

I used a laptop for studying for Astronomy, and what I would do is I would make folders for each aspect of Astronomy that I needed to study (for instance, Deep Sky Objects, Stellar Evolution, Variable Stars, Exoplanets, Distance Calculations, Various mathematical calculations, H-R Diagram, etc.) Then, I put the resources in the appropriate folders. I agree with AlphaTauri that you should make sure whatever resource you're using is organized. It will make your life a whole lot easier when you're trying to find out what the absolute magnitude of T-Tauri is while answering a question on exoplanet mass calculations. It will make test-taking so much more streamlined and allow you time to think.

How do you access the powerpoint that Donna was talking about on the aavso website? Is it the same powerpoint as the one form 2015, or is there a new 2016 one?

Considering the topics for this year are the same as last year and the AAVSO website for SciOly hasn't been updated since July, it probably is the 2015 one? I don't see a powerpoint on the Chandra website either.

Here is the Chandra 2016 webinar, btw:

### Re: Astronomy C

I haven't been able to find many good explanations for the calculation of an exoplanet's surface temperature. I have found $T^4=L(sun)*(1-albedo)/16πd^2σ$ and a few others, often including the radius of the planet. Can someone post a link or an explanation of how to solve these problems?

Forgive me for linking to something I wrote myself, but I think it explains it well. Hope this helps.

Hm, that post makes me wonder if you wouldn't mind updating the onward to the edge blog if you're gonna end up making astro posts anyway...

Some comments on your notation. Most astronomers simply say "F" of some sort rather than "energy flux", E_f. E_f might be a bit confusing if you've ever done conservation of energy in physics or various other instances (it can get confusing when you speak in flux density...I don't want to get into it'd probably be confusing). Physicists also use "I" for intensity, though I personally like to think of that as current. Just a bit of (semi-important) semantics! Thankful the astro peoples on this website still exist .

Referring to the Chandra videos for this year:
There is usually a powerpoint that goes with the videos. Has anyone seen that for this year?

The audio seems very poor to me, I'm having a hard time understanding what she is saying.
