The discovery of close in, giant planets (hot Jupiters) with orbital angularmomentum vectors misaligned with respect to the rotation axis of their hoststars presents problems for planet formation theories in which planets form indiscs with angular momentum vectors aligned with that of the star. Violent,high eccentricity migration mechanisms purported to elevate planetary orbitsabove the natal disc plane predict populations of proto-hot Jupiters which havenot been observed with Kepler. Alternative theories invoking primordialstar-disc misalignments have recently received more attention. Here, therelative alignment between stars and their protoplanetary discs is assessed forthe first time for a sample of 20 pre-main-sequence stars. Recently publishedrotation periods derived from high quality, long duration, high cadence K2light curves for members of the $\rho$ Ophiuchus and Upper Scorpius starforming regions are matched with high angular resolution observations ofspatially resolved discs and projected rotational velocities to determinestellar rotation axis inclination angles which are then compared to the discinclinations. Ten of the fifteen systems for which the stellar inclinationcould be estimated are consistent with star-disc alignment while five systemsindicate potential misalignments between the star and its disc. The potentialfor chance misalignment of aligned systems due to projection effects andcharacteristic measurement uncertainties is also investigated. While theobserved frequency of apparent star-disc misalignments could be reproduced by asimulated test population in which 100% of systems are truly aligned, thedistribution of the scale of inferred misalignment angles could not.
