Re: Astronomy C

Thank you for the confirmation, Tad! The info on astronomy sometimes changes so quickly, I just wanted to be sure. Separate question: When you are given a radial velocity graph that only has phase across the bottom, how do you determine the period? The phase is a portion of the period, right? But ho...

Re: Astronomy C

Regarding HR 8799, the webinar slides say this system has 5 planets, but I'm only seeing info that says 4 planets. Is 4 correct, or am I missing a planet somewhere? ;)

Your're right! I'm used to you having all the answers... ;)

Andrewwski, my apologies and thanks!

Correct, Magik! Also, they are like insect cocoons because they protect the interior from outside radiation and stellar winds. :)

Re: Astronomy C

Just went to regionals. After spending hours on my binder they used last year's test! It was about variables and didn't have a single question about the DSO's! We were pretty frustrated. I'm not sure some of the math questions were even possible. One question gave us the radius of an exoplanet and ...

Re: Astronomy C

A. Which of your objects is a type of object that has been described as “similar to insect cocoons”? B. Why is it described that way? Sorry, but since arvind_r answered my last question, it should be his/her turn to ask. If he takes too long a time (a week roughly) then you may go ahead. Sorry, I d...

Re: Astronomy C

Regarding high mass versus low mass stars and their affect on planets: First question - one of the objects connected a short orbital period with the low mass of the host star. I'm not understanding how that is connect. Second question - I always thought that higher mass stars were more likely to hav...
