cds-question@unistra.frpre-main-sequence-starslate-type-starsUsing the kinematically unbiased technique described in Binks, Jeffries & Maxted (2015MNRAS.452..173B, Cat. J/MNRAS/452/173), we present optical spectra for a further 122 rapidly-rotating (rotation periods < 6 days), X-ray active FGK stars, selected from the SuperWASP survey. We identify 17 new examples of young, probably single stars with ages of <200Myr and provide additional evidence for a new northern hemisphere kinematic association: the Pisces Moving Group (MG). The group consists of 14 lithium-rich G- and K-type stars, that have a dispersion of only ~3km/s in each Galactic space velocity coordinate. The group members are approximately co-eval in the colour-magnitude diagram, with an age of 30-50 Myr, and have similar, though not identical, kinematics to the Octans-Near MG.2018MNRAS.473.2465Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/473/2465CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/452/173 : Nearby young stars in Northern hemisphere (Binks+, 2015)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/473/2465https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/473/2465http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/473/2465https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/473/2465https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/473/2465http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/473/2465GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/473/2465/suppdata (Compiled astrometric, kinematic, spectroscopic and photometric data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/473/2465/suppdata?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/473/2465/suppdata?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/473/2465/suppdata?GETtext/xml+votable180.050000true1.652358343143.70786136910.0055555555555555566/2167 2305 2455 2733 2782 2804 8663 8951 9164 9187 9276 9337 9402 9405 9458 9512 9514 9551 9625 9637 9773 9790 9985 10052 10077 10103 10109 10190 10303 10382 10587 10653 10800 10814 11035 12377 12436 12514 12568 12717 12770 12885 13140 13320 13391 13427 13525 13636 13648 13714 13743 13885 13970 14858 14888 15038 15067 15090 17306 18549 18902 18938 19452 19479 19948 20007 20021 20148 20162 20300 20377 20473 28092 28448 30895 31805 31812 31940 31997 32374 32561 32566 32617 32670 32688 44892 490547.952274030004205e-20 4.920466254354166e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/473/2465?format=asciidefaultJ/MNRAS/473/2465/suppdataCompiled astrometric, kinematic, spectroscopic and photometric datacPM[1/3] Proper motion code (8)meta.codeintrecnoRecord number assigned by the VizieR team.
