Hello,
I am trying to revise for my Solar System exam and going through a past paper i have a question relating to something that we don't seem to have covered:
"By estimating the energy output of the Sun's corona (in watts), comment on whether can be treated as a blackbody radiator. (Assume a coronal radius = 2Rsun)"
I understand what a blackbody is, and i understand how i can estimate the energy output of the Sun by calculating it luminosity http://en.wikipedia.org/wiki/Luminosity#Computing_between_brightness_and_luminosity"
However, i don't see the link between luminosity and black body. By getting a value of x Watts how can i say yes this is black body or no it isnt?
Thanks for any help
