cds-question@unistra.frdwarf-starsm-starsWe have analysed 10 months of public data from the Kepler space mission to measure rotation periods of main-sequence stars with masses between 0.3 and 0.55M_{sun}_. To derive the rotational period, we introduce the autocorrelation function and show that it is robust against phase and amplitude modulation and residual instrumental systematics. Of the 2483 stars examined, we detected rotation periods in 1570 (63.2%), representing an increase of a factor of ~30 in the number of rotation period determination for field M dwarfs. The periods range from 0.37 to 69.7d, with amplitudes ranging from 1.0 to 140.8mmag. The rotation period distribution is clearly bimodal, with peaks at ~19 and ~33d, hinting at two distinct waves of star formation, a hypothesis that is supported by the fact that slower rotators tend to have larger proper motions. The two peaks of the rotation period distribution form two distinct sequences in period-temperature space, with the period decreasing with increasing temperature, reminiscent of the Vaughan-Preston gap. The period-mass distribution of our sample shows no evidence of a transition at the fully convective boundary. On the other hand, the slope of the upper envelope of the period-mass relation changes sign around 0.55M_{sun}_, below which period rises with decreasing mass.2013MNRAS.432.1203Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/432/1203CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/133 : Kepler Input Catalog (Kepler Mission Team, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/432/1203https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/432/1203http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/432/1203https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/432/1203https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/432/1203http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/432/1203GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/432/1203/table2 (M-dwarfs with detected rotation periods)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/432/1203/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/432/1203/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/432/1203/table2?GETtext/xml+votable180.050000true291.3348436.806438060.005555555555555556Cone search capability for table J/MNRAS/432/1203/table3 (Objects identified as likely giants)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/432/1203/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/432/1203/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/432/1203/table3?GETtext/xml+votable180.050000true291.2416136.749881940.005555555555555556Cone search capability for table J/MNRAS/432/1203/table4 (Objects with 2 distinct periods)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/432/1203/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/432/1203/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/432/1203/table4?GETtext/xml+votable180.050000true291.0638736.635811110.005555555555555556Cone search capability for table J/MNRAS/432/1203/table5 (Objects with no rotation period detection)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/432/1203/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/432/1203/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/432/1203/table5?GETtext/xml+votable180.050000true290.8527536.869160.0055555555555555564/922-923 933-935 944-946 5/3645-3647 3683 3704 3706 3729-3730 3788-3789 3792 6/14567 14573 14575 14577-14579 14730-14731 14738 14744 14746-14747 14750-14751 14792 14794-14795 14828 14830 14914-14915 14924-14926 15040-15041 15043-15045 15057 15059-15062 15160-15161 15172-15174 15178 15200 15232https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/432/1203?format=asciiOpticaldefaultJ/MNRAS/432/1203/table2M-dwarfs with detected rotation periodsrecnoRecord number assigned by the VizieR team.
