Stellar Colors & Spectra: Having experienced one too many Minnesota winters, after college you move to Tucson, Arizona to check out life in the desert. Some friends invite you to join them on a tour of Kitt Peak National Observatory on a mountain just south of town. Coincidentally, you are in the 4-meter Mayall telescope “warm room” (computer room) talking with the observer about her project to measure rotational speeds of disk galaxies when she gets a call from her thesis advisor, who says “I’ve just got an inside scoop on a very interesting star that seems to be within the Butterfly cluster. I want you to take some observations of it in order to learn everything you can about this star tonight.” Flustered and sleep-deprived, the observer flippantly asks your group if anyone knows anything about how to study stars and you – having taken Phys 1053 in college – seize the opportunity and offer to help!
She tells you the telescope can detect optical and near-infrared light, has a full set of filters available (U, B, V, R and I), and has two instruments to choose from: an imager and a spectrograph. The two of you get right to work, and by morning you are the leading authorities on the properties of this interesting star. Write a report for the advisor explaining what observations you made and how they lead to determinations of specific properties of the star such as temperature, luminosity, composition, radius, distance, mass, & age. (You may invent information about the star. If you do, try to be consistent; for example, if a star is cool and luminous it can’t be small.)
this needs to be 800-1200 please help me!!!!!
I do not expect some one to do this but a push in the right direction would be nice I have really no clue where to go thanks!
yes I will give credit where it is due do not worry about that
