Calculate the minimum mass of an X-ray binary

  1. Oct 16, 2015 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations
    n/a

    3. The attempt at a solution
    I don't know how to start part A and part B depends on part A. How does one calculate a lower mass limit? Is it the lower limit of an integral? I also don't understand how there can be two periods (one at 0.714 seconds and the other at 3.89 days). Do I use simple harmonic motion? My teacher never covered anything this complicated before. Thank you for your time.

    How is this advanced? This is my introductory astronomy class, and it's very frustrating.

    Not everybody on this site is a budding astronomer. :cry:

    Your OP doesn't indicate any relevant equations. Are you sure that's the case with this problem?
