cds-question@unistra.frvariable-starsx-ray-sourcesphotometryWe present a catalog of 307 optical counterparts of the bright ROSAT X-ray sources, identified with the ASAS North survey data and showing periodic brightness variations. They all have declination north of -25{deg}. Other data available from the literature for the listed stars are also included. All the tabulated stars are new variables, except for 13 previously known, for which the revised values of periods are given.2013AcA....63...53Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AcA/63/53CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIX/10 : ROSAT All-Sky Bright Source Catalogue (1RXS) (Voges+ 1999)II/264 : ASAS Variable Stars in Southern hemisphere (Pojmanski+, 2002-05)J/AcA/62/67 : ASAS photometry of ROSAT sources (Kiraga, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AcA/63/53https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AcA/63/53http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AcA/63/53https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AcA/63/53https://vizier.iucaa.in/viz-bin/votable?-source=J/AcA/63/53http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AcA/63/53GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AcA/63/53/catalog (Catalog of the 307 periodic variables)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AcA/63/53/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/AcA/63/53/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AcA/63/53/catalog?GETtext/xml+votable180.050000true5.315256950.88998420.0055555555555555566/92 138 195 263 511 1182 1330 1467 1506 1516 1576 1647 1662 1717 1773 1782 1853 1870 1872 1893 1953 1961 1990 2194 2305 2354 2388 2455 2512 2646 2804 2840 2863 2939-2940 2942 3018 3046 3056 3081 3097 3109 3152 3166 3204 3275 3289-3290 3308 3329 3409 3441 3570 3688 3739 3742 3789 3875 3881 3913 3928 3961 4012-4013 4669 5333 5578 5754 5791 5823 5854 5984 6037 6223 6244 6305 6307 6502 6689 6777 6814 6885 6887 6902 6907 6909 6943 7100 7110 7141 7158 7163 7204 7269 7342 7448 7494 7572 7583 7613 7681 7884 7928 7953 7968 7980 7988 8025 8063 8097 8135 8185 8497 8947 9323 9662 9849 9869 9917 9932 9964 10412 10619 10663 10718 10819 10847 10934 10960 10984 11062 11185 11214 11367 11490 11601 11624 11669 11703 11725 11735 11789 11800 11837 11850 11880 11978 11988 12010 12038 12122 12124 12132 12142 12266 12517 12635 13017 13187 13196 13208 13234 13251-13252 13261 13264 13266 13280 13305 13407 13576 13684 13714 13725 13802 13813 13868 14010 14014 14041 14076 14085 14092 14129 14139 14174 14200 14303 14322 14427 14493 14506 14520 14596 14611 14620 14643 14671 14792 14821 14829 14858 14875 15011 15077 15181 15194 15197 15253 15276 15293 15302 15347 15371 15390 15401 15426 15429 15496 15533 15541 15559 15585 15655 15674 15686 15746 15763 15775 15783 15844 15890 15908 15976 16004 16029 16063 16141 16172 16189 16206 16209 16213 16215 16217 16247 16275 16324 16345 16358 16369 17533 17940 18203 18290 18374 18473 18740 18758 19077 19608 20472 20969 21346 21491 22218 22856 22860 22966 23400 23845 24063 24127 24167 24197 24212 24254 24318 24405 24481 24989 28526 29289 29681 29854 30355 30982 31450 31747 32076 36778 40251 40388 40534 44397 48553 48874 490881.5062136169708525e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AcA/63/53?format=asciiX-rayOpticaldefaultJ/AcA/63/53/catalogCatalog of the 307 periodic variablesRemRemarks (2)meta.notecharrecnoRecord number assigned by the VizieR team.
