We report rotation periods for 441 stars within this field and determine their cluster membership and binarity based on a decade-long radial velocity survey, proper-motion measurements, and multiband photometric observations. We find that 310 of the stars with measured rotation periods are late-type members of M35. The distribution of rotation periods for cluster members span more than 2 orders of magnitude from ~0.1 to 15 days, not constrained by the sampling frequency and the timespan of the survey. With an age between the zero-age main sequence and the Hyades, and with ~6 times more rotation periods than measured in the Pleiades, M35 permit detailed studies of early rotational evolution of late-type stars. Nearly 80% of the 310 rotators lie on two distinct sequences in the color-period plane, and define clear relations between stellar rotation period and color (mass). The M35 color-period diagram enables us to determine timescales for the transition between the two rotational states, of ~60Myr and ~140Myr for G and K dwarfs, respectively.2009ApJ...695..679Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/695/679CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/244 : Catalog of Stellar Rotational Velocities (Glebocki+ 2005)J/ApJ/546/1006 : VRI photometry of M35 (Barrado y Navascues+, 2001)J/MNRAS/306/361 : UBVI CCD photometry of M35 (NGC 2168) (Sung+ 1999)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/695/679https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/695/679http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/695/679https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/695/679https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/695/679http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/695/679GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/695/679/table2 (Data for the 441 stars with measured rotation periods in the field of M35)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/695/679/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/695/679/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/695/679/table2?GETtext/xml+votable180.050000true92.1130666724.354480830.0055555555555555566/24339 24344 243453.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/695/679?format=asciiOpticalInfrareddefaultJ/ApJ/695/679/table2Data for the 441 stars with measured rotation periods in the field of M35recnoRecord number assigned by the VizieR team.
