Compilation of stellar rotation data
Listed in IVOA Registry (Virtual Observatory)
The distribution of the stellar rotation axes of 113 main sequence stars in the open cluster Praesepe are examined by using current photometric rotation periods, spectroscopic rotation velocities, and estimated stellar radii.
Description
Three different samples of stellar rotation data on spotted stars from the Galactic field and two independent samples of planetary hosts are used as control samples to support the consistency of the analysis.
Considering the high completeness of the Praesepe sample and the behavior of the control samples, we find that the main sequence F-K stars in this cluster are susceptible to rotational axis alignment. Using a cone model, the most likely inclination angle is 76+/-14{deg} with a half opening angle of 47+/-24{deg}. Non-isotropic distribution of the inclination angles is preferred over the isotropic distribution, except if the rotation velocities used in this work are systematically overestimated.

We found no indication of this being the case on the basis of the currently available data.
