A spectroscopically confirmed Gaia-selected sample of 318 new young stars within ~200pc

While precise parallaxes and proper motions for nearby stars are made available by Gaia, spectroscopic youth indicators for a large fraction of low-mass young stars are still missing. Here we present our observations of 318 new young late K and early M dwarfs within ~200pc that have a detectable lithium line and are not found in the known catalogs of young stars. We also provide measurements of H\(\alpha\) and calcium H&K emission and report on additional 126 stars which have no detectable lithium but signs of stellar activity indicating youth. Radial velocities were measured for 756 observed overluminous young star candidates. To infer the origin of these young stars, we are using Chronostar, a novel technique for kinematic characterisation of stellar and their age determination. Our first results in the Scorpius-Centaurus region reveal its complex substructure
