Thank you Michel! This is exactly what my students needed!

The second formula at the end can be even further simplified, by substituting a with a1+a2. Then we will get, m1/m2 = a2/a1 which is easier to remember, or even, m1*a1 = m2*a2.

no binary system, how can you find the mass of one star system?

Sir i have an idea to find the mass of a single stat.

There is a formula:

L/L0=(m/M0 )⁴

We can re-arrenge this equation and say that:

M/m= 4 th root of L/L0

How do we calculate the center mass to obtain the A, A1, and A2 values if we are trying to calculate the mass of the two stars?
