# Case B: Aligned Spin

## Detail

In case B, the dimensionless spin of the primary is $S_{1}/{M_1}^2 = 0.5$ and is aligned with the orbital angular momentum. The dimensionless spin of the secondary is $S_{2}/{M_2}^2 = 0.5\frac{36M_{\odot}}{29M_{\odot}}\approx 0.62$ and is antialigned with the orbital angular momentum.
