Homework Statement


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.


Homework Equations



not important for my question


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.
 
To solve this, I first used the units to work out that a= m* a/m, i.e. t=z/λ. This would allow you to determine the time duration within an interval section by section and then add this to the previous ones to obtain the age of the respective layer. However, this would require a constant thickness per year for each interval. However, since this is most likely not the case, my next consideration was that the age must be the integral of a 1/λ(z) function, which I cannot model.
