Astrophysics?

What is the color index of a star at a distance of 150 pc with mv = 7.55 and Mb = 2.00?|||Hmmm good question. I think first you need to covert the Absolute b mag to apparent (is a bolometric conversion required as well?) then just subtract mv from the calculate mb.





If only I had my text book here :)
