cds-question@unistra.frradio-sourcesvariable-starsphotometryWe present optical lightcurves of 428 periodic variable stars coincident with ROSAT X-ray sources, detected using the first run of the SuperWASP photometric survey. Only 68 of these were previously recognised as periodic variables. A further 30 of these objects are previously known pre-main sequence stars, for which we detect a modulation period for the first time. Amongst the newly identified periodic variables, many appear to be close eclipsing binaries, their X-ray emission is presumably the result of RS CVn type behaviour. Others are probably BY Dra stars, pre-main sequence stars and other rapid rotators displaying enhanced coronal activity. A number of previously catalogued pulsating variables (RR Lyr stars and Cepheids) coincident with X-ray sources are also seen, but we show that these are likely to be misclassifications. We identify four objects which are probable low mass eclipsing binary stars, based on their very red colour and light curve morphology.2007A&A...467..785Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/467/785CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIX/10 : ROSAT All-Sky Bright Source Catalogue (1RXS) (Voges+ 1999)IX/29 : ROSAT All-Sky Survey Faint Source Catalog (1RXS) (Voges+ 2000)IX/30 : Second ROSAT PSPC Catalog (2RXP) (ROSAT, 2000)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/467/785https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/467/785http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/467/785https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/467/785https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/467/785http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/467/785GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/467/785/table1 (Previously classified variable stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/467/785/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/467/785/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/467/785/table1?GETtext/xml+votable180.050000true4.957958321.94786110.005555555555555556Cone search capability for table J/A+A/467/785/table2 (Newly identified variable stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/467/785/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/467/785/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/467/785/table2?GETtext/xml+votable180.050000true3.489916735.04538890.0055555555555555566/350 358 368 472-474 478 496 505 508 510 744 746 761 783 794 797 838 847 861-862 874 917 931 940 946 987 999 1005 1011 1027 1030-1031 1038 1050-1052 1057-1058 1074 1078 1080 1099 1105 1111 1114 1118 1139 1152 1159 1165 1168 1170 1172 1174 1185 1198 1212 1215 1232 1234 1245 1273 1282 1293 1327 1358 1382 1392 1420 1457 1538-1539 1542 1556 1596 1611 2052 2075 2093 2098 2101 2110 2119 2145 2155 2171 2220 2223 2293-2294 2311 2321-2322 2389 2412 2435-2436 2472 2476 2564 2574 5458 5481 6279 6282 6320 6764 8558 8627 8663 8687 8698 8915 8950-8951 9052 9135 9142 9164 9187 9221 9227 9231 9239 9249 9254 9276 9289 9294 9300 9311 9320 9335 9337 9353-9354 9365 9385 9402 9404-9405 9422 9432 9436 9458 9484 9494 9497 9502 9506 9512 9514 9551 9558 9570 9616 9625 9637 9648 9703 9705 9710 9712 9724 9773 9784 9786 9790 9812 9831 9920 9985 10049 10052 10071 10103 10109 10183 10253 10301 10303 10382 10391-10392 10401 10412 10448 10469 10513 10520 10551 10560 10575 10582 10587 10634 10639 10658 10771 10786 10793 10797 10800 10814 11015 11031 11033 11395 12335 12337 12340 12359 12377 12400 12405 12436 12463-12464 12473-12474 12480 12511-12512 12514 12522 12567 12569 12597 12650 12672 12710 12770 12777 12790 12925 13126 13188 13314 13320 13389 13391 13405 13414 13427 13429 13450 13457 13460 13502 13511 13525 13603 13609 13720 13730 13824-13825 14882 14888 14978 14984 15005 15029 15036 15038 15067 15078 15087 15232 15241 18431 19427 19452 19454 19782 19791 19805 19819 19879 19888 19897 19902 19931 19948 19950 20071 20086 20145 20162 20168-20169 20178 20202 20209 20217 20220 20287 20300 20327 20348 20358 20377-20378 20381 20384 20392 20430 20438 23895 23980 23983 23996 24175 24247 24272-24273 24280-24281 24283 24286 24296-24297 24327 24343 24362 24414 24517 27997 28085 28092 28103 28114 28127 28131 28448 28516 28535 28540-28541 28643 28655 31805 31812 31843 31893-31894 31936 31940 31955 31970 31991 31997 32135 32141 32183 32191 32320 32329 32356 32370 32373 32411 32414 32432 32441 32454 32462 32472 32474 32492 32500 32520-32521 32526-32527 32531 32541 32544-32545 32566 32598 32601 32638 32651 32657 32670 32674 32688 32695 32706 32717 32720 32734 32736 32754 32759https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/467/785?format=asciiOpticalRadiodefaultJ/A+A/467/785/table1Previously classified variable starsrecnoRecord number assigned by the VizieR team.
