cds-question@unistra.fropen-star-clusterseclipsing-binary-starsphotometryWe report the results of a study of archival SuperWASP light curves for stars in Scorpius-Centaurus (Sco-Cen), the nearest OB association. We use SuperWASP time-series photometry to extract rotation periods for 189 candidate members of the Sco-Cen complex and verify that 162 of those are members of the classic Sco-Cen subgroups of Upper Scorpius (US), Upper Centaurus-Lupus (UCL), and Lower Centaurus-Crux (LCC). This study provides the first measurements of rotation periods explicitly for large samples of pre-main-sequence (pre-MS) stars spanning the UCL and LCC subgroups. Our final sample of 157 well-characterized pre-MS stars spans ages of ~10-20Myr, spectral types of ~F3-M0, and masses of M~=0.3-1.5 M_{sun}_^N^. For this sample, we find a distribution of stellar rotation periods with a median of P_rot_~=2.4-days, an overall range of 0.2<P_rot_<8-days, and a fairly well-defined mass-dependent upper envelope of rotation periods. This distribution of periods is consistent with recently developed stellar angular momentum evolution models. These data are significant because they represent an undersampled age range and the number of measurable rotation periods is large compared to recent studies of other regions. We also search for new examples of eclipsing disk or ring systems analogous to 1SWASP J140747.93-394542.6 (J1407), but find none. Our survey yielded five eclipsing binaries, but only one appears to be physically associated with the Sco-Cen complex. V2394 Oph is a heavily reddened (A_V_~=5mag) massive contact binary in the LDN 1689 cloud whose Gaia astrometry is clearly consistent with kinematic membership with the Ophiuchus star-forming region.2017ApJ...844...66Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/844/66CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/844/66https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/844/66http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/844/66https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/844/66https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/844/66http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/844/66GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/844/66/table2 (Data for Sco-Cen main group members)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/844/66/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/844/66/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/844/66/table2?GETtext/xml+votable180.050000true168.3644167-45.39241670.005555555555555556Cone search capability for table J/ApJ/844/66/table3 (Data for other stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/844/66/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/844/66/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/844/66/table3?GETtext/xml+votable180.050000true168.6434583-44.30669440.005555555555555556Cone search capability for table J/ApJ/844/66/table1 (Periodogram analysis results)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/844/66/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/844/66/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/844/66/table1?GETtext/xml+votable180.050000true168.3644167-45.39241670.0055555555555555565/10673 11075 6/38189 38191 38203 38216 38232 38341 41972 41973 41981 42607 42611 42614 42615 42617 42618 42630 42634 42635 42658 42663 42664 42665 42671 42675 42679 42683 42685 42691 42696 42699 42700 42704 42705 42706 42708 42712 42715 42727 42728 42730 42735 42736 42737 42751 42766 42779 42787 42789 42792 42799 42800 42804 42809 42810 42812 42885 42888 42889 42924 42930 42952 42957 42970 42978 42983 42988 42990 42991 42992 42994 43000 43002 43230 43257 43258 43259 43294 43295 43321 43323 43326 43339 43341 43350 43356 43365 43366 43403 43412 43417 43427 43432 43433 43435 43441 43442 43452 43461 43475 43571 43573 43586 43598 43608 43610 43616 44032 44034 44035 44036 44038 44040 44048 44050 44051 44062 44063 44065 44069 44073 44074 44076 44081 44084 44104 44106 44113 44118 44289 44295 44297 44307 44308 44310 44312 44314 44316 44317 44319 44333 44337 44352 44353 44355 44356 44358 44359 44360 44362 44363 44365 44388 47828 479041.1166583743361574e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/844/66?format=asciiOpticaldefaultJ/ApJ/844/66/table2Data for Sco-Cen main group membersSWASPJSWASP identifier (HHMMSS.ss+DDMMSS.s)meta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
