Whether disc regulation also extends to stars with later spectral types still remains a matter of debate. Here, we present a star-disc interaction study in a sample of over 180 stars with spectral types M3 and later (corresponding to stellar masses <=0.3M_{sun}_) in young stellar cluster NGC 2264. Combining rotation periods from the literature, new and literature spectral types, and newly presented deep Spitzer observations, we show that stars with masses below 0.3M_{sun}_ with discs also rotate slower than stars without a disc in the same mass regime. Our results demonstrate that disc regulation still operates in these low-mass stars, although the efficiency of this process might be lower than in higher mass objects. We confirm that stars with spectral types earlier and later than M2 have distinct period distributions and that stars with spectral types M5 and later rotate even faster M3 and M4-type stars.2019MNRAS.487.2937Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/487/2937CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/114/2644 : UBVRIHa photometry of NGC2264 (Sung+, 1997)J/AJ/127/1117 : Halpha emission-line stars in NGC2264 (Reipurth+, 2004)J/A+A/590/A78 : NGC2264 weak-line T Tauri lithium abundances (Bouvier+, 2016)J/A+A/609/A10 : NGC2264 structure and star formation history (Venuti+, 2018)J/ApJ/821/8 : Spectroscopic binary population of ONC and NGC2264J/A+A/670/A37 : Spatial and dynamical structure of NGC2264 (Flaccomio+, 2023)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/487/2937https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/487/2937http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/487/2937https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/487/2937https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/487/2937http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/487/2937GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/487/2937/table1 (Periods, photometry and spectral types for NGC 2264 members)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/487/2937/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/487/2937/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/487/2937/table1?GETtext/xml+votable180.050000true100.1659.297610.005555555555555556Cone search capability for table J/MNRAS/487/2937/tablea1 (Spectral types, H{alpha} and CaII presences in field stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/487/2937/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/487/2937/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/487/2937/tablea1?GETtext/xml+votable180.050000true100.28429.56930.0055555555555555566/23636-23637 236392.367228618189496e-19 3.3785437584409506e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/487/2937?format=asciiMillimeterdefaultJ/MNRAS/487/2937/table1Periods, photometry and spectral types for NGC 2264 membersSimbadNameSimbad column added by the CDSmeta.idcharnullablerecnoRecord number assigned by the VizieR team.
