Homework Help: Amplitude of spectroscopic signal

  1. Oct 5, 2011 #1
    1. The problem statement, all variables and given/known data
    What is the amplitude of the spectroscopic signal if the inclination is 45 degrees?
    Mass star = 1 mass of sun = 1.9891 x 10^30kg
    Mass Planet = 10 mass Earth = 5.9736 x 10^25kg
    Orbital period = 1 year

    2. Relevant equations

    I'm not sure about even what equation to use.

    3. The attempt at a solution

    I calculated the velocity of both masses, with velocity of the planet equalling 29.7km/s and the velocity of the star being 0.891km/s.
