1. The problem statement, all variables and given/known data
The question is really long, so I am going to summarize the information that I have for the problem. I have two stars with their radial velocities Star1= 5.4 and Star2 = 22.4. The time period between first contact and minimum light is .58 days, the length of primary minimum is 0.64 days, and the apparent bolometric magnitudes are: maximum = 5.4 primary minimum = 9.2 secondary minimum = 5.44 magnitudes. Assume circular orbit.

Find the individual ratio

What is an individual ratio? I just don't understand what it is asking for.

2. Relevant equations

not important for my question

3. The attempt at a solution

none, I don't understand the question. I understood when it asked for ratio of masses and individual masses, and the ratio of effective temperatures. I also have all the equations I will need.

Thanks, I hate it when the only part of an assignment that is too "hard" is trying to understand what it is asking

I apologize, I was informed that that was a typo on the HW sheet, and it was actually asking for the radii and not the ratio.
