cds-question@unistra.frpre-main-sequence-starsx-ray-sourcesradial-velocityWe present the first results of an ambitious ground-based observation programme conducted on 1-4m class telescopes. Our sample consists of 1097 active and presumably young stars, all of them being optical (Tycho Catalogue) counterparts of ROSAT All- Sky Survey X-ray sources in the northern hemisphere. In this paper, we concentrate on the optically brightest (VT<=9.5m) candidates (704 objects).We acquired high-resolution optical spectroscopy in the H{alpha} and/or lithium spectral regions for 426 of such stars without relevant data in the literature. We describe the star sample and the observations and we start to discuss the physical properties of the investigated stars.2009A&A...504..829Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/504/829CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/454/301 : Radial velocities of 6 binaries (Frasca+, 2006)J/A+A/490/737 : Radial velocities of 3 RasTyc new triple system (Klutsch+ 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/504/829https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/504/829http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/504/829https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/504/829https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/504/829http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/504/829GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/504/829/cbssb (Combined table from original tables)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/504/829/cbssb?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/504/829/cbssb?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/504/829/cbssb?GETtext/xml+votable180.050000true9.3855.2252780.0055555555555555566/861 871 873 888 893 964 975 987 1149 1227 1248 1260 1279 1344 1389 1431 1441 1506 1531 1553 1571-1572 1578 1598 1647 1688 1701 1707-1708 1710-1711 1739 1748 1787 1794 1897 1919 1935 1947 1953 1979 1984 2014 2030 2169 2261 2305 2366 2418 2512 2531 2535-2536 2547 2618 2636 2648 2671 2694 2811 2816 2919 2949 2961 2974 2984 2988 2990-2991 3060 3063 3069 3081 3137 3146 3162 3296 3309 3325 3331 3335 3383-3384 3397 3399 3401 3441 3451 3494 3500 3532 3564 3579 3605-3606 3638 3663 3683 3695 3703 3715 3736 3763 3781 3828 3887-3888 3892 3913 3916 3925-3926 3961 3968 6254 6387 6589 6735 6792 6801 6825 6831 6907 6930 6932 6976 7058 7094 7159 7812 7816 7819 7874 7887 7891 7922 7925 8104 8124 8184 8290 8294 8297-8298 8454 8466 8583 8652 8655 9045 9220 9224 9235 9301 9395 9411 9440 9446 9476 9498 9587 9604 9610 9844 9870 9935 9965 9974 10004 10077 10082 10107 10194 10221 11367 11391 11510-11511 11735-11736 11747 11751 12080 12092 12228 12245 12343 12388 12436 12489 12511 12631 12634 12654 12662 12694 12770 12792-12793 12808 12846 13016 13039 13045 13088 13101 13106 13110 13112 13114 13122 13161 13176 13196 13243 13287 13290 13462 13538 13547 13563 13623 13650 13674 13720 13749 13753 13769 13784 13802 13805 13811 13868 13877 13963 13966 14038 14058 14114 14134 14204 14233 14237 14270 14289 14303 14334 14361 14400 14437 14441 14453 14470 14476 14553 14562 14571 14596 14604 14649 14697 14724 14735 14763 14771 14790 14805 14888 14907 14931 14940 15007 15041 15103 15137 15154 15223 15234 15241 15305 15363 15368-15369 15372-15373 15380 15410 15466 15479 15486 15530 15595 15648 15684 15697 15703 15735 15751 15755 15864 15870 15887 15890 15993 16002 16008 16034 16059 16063 16102 16209 16253 16275 16329 17355 18640 18693 18695 18840 18856 18884 18888-18889 18980 18991 19053 19081 19105 19108 19186 19205 19219 19409 19414 19417 19432 19446 19448 20005 20108 20402 20464 20476 24519 24545 29439 29671 30040 30054 30093 30130 30176 30181 30195-30196 30201 30305 30331 30363 30395 30422 30447 30484 30540 30668 30828 30904 30914 30968 30978 31094 31104 31164 31287 31358 31399 31449 31501 31541 31548 31550-31551 31617 31632 31649 31666-31667 31697 31708 31740 31752 31812 31873 31886 31902 31913 31922 32006 32032 32102 32182 32257 32300 32345 32368 32378 32412 32415 32585 32601 32614 32617 32633 32735 44909 44912 49062 49084 49089 49118https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/504/829?format=asciiX-rayOpticaldefaultJ/A+A/504/829/cbssbCombined table from original tablesrecnoRecord number assigned by the VizieR team.
