cds-question@unistra.fropen-star-clustersphotometryproper-motionsvisible-astronomytrigonometric-parallaxWe present the results of photometric surveys for stellar rotation in the Hyades and in Praesepe, using data obtained as part of the SuperWASP exoplanetary transit-search programme. We determined accurate rotation periods for more than 120 sources whose cluster membership was confirmed by common proper motion and colour-magnitude fits to the clusters' isochrones. This allowed us to determine the effect of magnetic braking on a wide range of spectral types for expected ages of ~600Myr for the Hyades and Praesepe. Both clusters show a tight and nearly linear relation between J-Ks colour and rotation period in the F, G and K spectral range. This confirms that loss of angular momentum was significant enough that stars with strongly different initial rotation rates have converged to the same rotation period for a given mass, by the ages of Hyades and Praesepe.2011MNRAS.413.2218Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/413/2218CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/354/881 : Praesepe + Hyades Am stars RV (Debernardi+ 2000)J/A+A/367/111 : A Hipparcos study of the Hyades cluster (de Bruijne+, 2001)J/AJ/127/3579 : Radial velocities of Hyades stars (Paulson+, 2004)J/MNRAS/257/257 : Proper motions in the Hyades (Reid 1992)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/413/2218https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/413/2218http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/413/2218https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/413/2218https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/413/2218http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/413/2218GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/413/2218/table1 (Hyades SuperWASP fields used in this survey)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/413/2218/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/413/2218/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/413/2218/table1?GETtext/xml+votable180.050000true49.024.16670.005555555555555556Cone search capability for table J/MNRAS/413/2218/hyades (Hyades members with SuperWASP rotation periods)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/413/2218/hyades?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/413/2218/hyades?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/413/2218/hyades?GETtext/xml+votable180.050000true54.395708321.34316670.005555555555555556Cone search capability for table J/MNRAS/413/2218/praesepe (Praesepe members with SuperWASP rotation periods)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/413/2218/praesepe?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/413/2218/praesepe?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/413/2218/praesepe?GETtext/xml+votable180.050000true127.924708326.11138890.0055555555555555565/1174 6/260 269 272 287 311 320-321 323 326-327 339-340 342 357 373 383 450 456 485 788 1025 1045-1046 1048 1058 1065 1307 4335 4349 4677 4684-4685 4687 4720-4721 4723-4724 4726 4732 5000 5008 23023 23035 23037 23132 23281 23313 23362 23368 23393 23408 23418 23440 23444 23478 23487 23490 23492 23499 23501 23504-23505 23507 23511-23512 23518 23523 23525 23529 23532-23533 23536-23537 23544-23545 23547-23548 23550 24088 24114 24123 24192 24200-24202 24204 24207 24242 244898.650015785639275e-20 9.710690472292815e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/413/2218?format=asciiOpticaldefaultJ/MNRAS/413/2218/table1Hyades SuperWASP fields used in this surveyrecnoRecord number assigned by the VizieR team.
