Are the spin axes of stars randomly aligned within a cluster?

We investigate to what extent the spin axes of stars in young open clusters are aligned. Assuming that the spin vectors lie uniformly within a conical section, with an opening half-angle between λ= 0° (perfectly aligned) and λ= 90° (completely random), we describe a Monte Carlo modelling technique t...
