Left: W2 vs. proper motion for new high proper motion candidates (μ/σ _μ > 5) detected with multi-epoch astrometry from WISE. Right: the final sample of candidates (Table 1), consisting of the candidates that have stellar colors in the WISE bands (Figure  1) and that are not rejected as motionless stars by other available data. All but one of these objects are detected by 2MASS. A companion to the Sun at a distance of <1 pc would exhibit a proper motion of 4'' yr ⁻¹ in these data. One object is in that range, but its motion is inconsistent with the purely parallactic motion expected for a solar companion.
