The past two decades have seen dramatic progress in our knowledge of the population of young stars of age < 200 Myr that lie within 150 pc of the Sun .
These nearby , young stars , most of which are found in loose , comoving groups , provide the opportunity to explore ( among many other things ) the dissolution of stellar clusters and their diffusion into the field star population .
Here , we exploit the combination of astrometric and photometric data from Gaia and photometric data from GALEX ( UV ) and 2MASS ( near-IR ) in an attempt to identify additional nearby , young , late-type stars .
Specifically , we present a sample of 146 GALEX UV-selected late-type ( predominantly K-type ) field stars with Gaia -based distances < 125 pc ( based on Gaia Data Release 1 ) that have isochronal ages < 80 Myr even if equal-components binaries .
We investigate the spectroscopic and kinematic properties of this sample .
Despite their young isochronal ages , only \sim 10 per cent ) of stars among this sample can be confidently associated with established nearby , young moving groups ( MGs ) .
These candidate MG members include 5 stars newly identified in this study .
The vast majority of our sample of 146 nearby young star candidates have anomalous kinematics relative to the known MGs .
These stars may hence represent a previously unrecognised population of young stars that has recently mixed into the older field star population .
We discuss the implications and caveats of such a hypothesis—including the intriguing fact that , in addition to their non-young-star-like kinematics , the majority of the UV-selected , isochronally young field stars within 50 pc appear surprisingly X-ray faint .
