Tull RVels, rotation periods and Inclinations

Among these, 53 stars have inclinations determined from projected rotational and equatorial velocities, and 21 stars predominantly hosting brown dwarfs have constraints on {Delta}i. Eleven of these (52_-11_^+10^% of the sample) are likely misaligned, while the remaining 10 host stars are consistent with spin- orbit alignment. As an ensemble, the minimum obliquity distribution between 10 and 250au is more consistent with a mixture of isotropic and aligned systems than either extreme scenario alone-pointing to direct cloud collapse, formation within disks bearing primordial alignments and misalignments, or architectures processed by dynamical evolution.

This contrasts with stars hosting directly imaged planets, which show a preference for low obliquities. These results reinforce an emerging distinction between the orbits of long- period brown dwarfs and giant planets in terms of their stellar obliquities and orbital eccentricities.
