Re: Astronomy C
Looking at radial velocity plots and this website: here eccentricity obviously affects the radial velocity of a star. However, I haven't been able to find an equation for eccentricity through a radial velocity curve. Is it calculable with just the curve?
If you somehow had the radial velocities ...

It seems bernard posted that the tentative focus for Chem Lab is thermodynamics and gas laws.

Re: Rubber & Winder Advice
Here are the building forums from last year: http://scioly.org/phpBB3/viewforum.php?f=188AstroJens wrote: Also how can I look at last year's forum on Wright Stuff. There is so many questions I have, and I'm sure that someone has probably answered them, so could someone tell me how to read last year's forums.

Re: Astronomy C
Star C has a transiting exoplanet orbiting it with an inclination of 66 degrees at an average distance of 2 AU. C has a mass of 30 Jupiter masses and radius 0.5 solar radii while the exoplanet has a mass of 4 Jupiter masses. If C has a density that is equal to that of the exoplanet...

Re: Wood
This from the Bridge Wood thread from earlier this year.
Does anyone know the best place to get balsa and bass wood? :)
I've used National Balsa and Specialized Balsa . I like that with Specialized Balsa I can select densities and grain (but at a higher price). I've also found that the wood cut ...

Re: Astronomy C
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.

3. Not sure if this is what you're looking for, but it has a higher density due to star-like formation while planets solely accumulate mass through accretion in the outskirts of the protoplanetary disk, this causes them to be ...
