cds-question@unistra.frmolecular-cloudsinfrared-photometrypolarimetrypre-main-sequence-starsinterstellar-mediumNear-infrared imaging polarimetry in the J, H, and Ks bands has been carried out for the protostellar cluster region around NGC 2264 IRS 2 in the Monoceros OB1 molecular cloud. Various infrared reflection nebula clusters (IRNCs) associated with NGC 2264 IRS 2 and the IRAS 12 S1 core, as well as local infrared reflection nebulae (IRNe), were detected. The illuminating sources of the IRNe were identified with known or new near- and mid-infrared sources. In addition, 314 point-like sources were detected in all three bands and their aperture polarimetry was studied. Using a color-color diagram, reddened field stars and diskless pre-main-sequence stars were selected to trace the magnetic field (MF) structure of the molecular cloud. The mean polarization position angle of the point-like sources is 81+/-29{deg} in the cluster core, and 58+/-24{deg} in the perimeter of the cluster core, which is interpreted as the projected direction on the sky of the MF in the observed region of the cloud. The Chandrasekhar-Fermi method gives a rough estimate of the MF strength to be about 100uG. A comparison with recent numerical simulations of the cluster formation implies that the cloud dynamics is controlled by the relatively strong MF. The local MF direction is well associated with that of CO outflow for IRAS 12 S1 and consistent with that inferred from submillimeter polarimetry. In contrast, the local MF direction runs roughly perpendicular to the Galactic MF direction.2011ApJ...741...35Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/741/35CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)J/AJ/138/963 : Rotation of NGC 2264 members (Baxter+, 2009)J/AJ/138/1116 : A Spitzer view of NGC 2264 (Sung+, 2009)J/AJ/135/441 : VRIH{alpha} photometry in NGC 2264 (Sung+, 2008)J/AJ/134/999 : X-ray observations of NGC 2264 (Dahm+, 2007)J/MNRAS/375/1220 : BVI photometry of young stars in 10 clusters (Mayne+, 2007)J/ApJ/671/605 : NGC 2264 and ONC PMS stars in the infrared (Cieza+, 2007)J/ApJ/642/972 : Star-forming core IR photometry in NGC 2264 (Young+, 2006)J/A+A/455/903 : ACIS-I observations of NGC 2264 (Flaccomio+, 2006)J/ApJ/648/1090 : Radial velocities of NGC 2264 stars (Furesz+, 2006)J/A+A/430/1005 : VRIH{alpha} photometry of NGC 2264 variables (Lamm+, 2005)J/AJ/129/829 : H{alpha} emission stars in NGC 2264 (Dahm+, 2005)J/A+A/417/557 : Rotation + variability of PMS Stars in NGC 2264 (Lamm, 2004)J/AJ/127/1117 : Halpha emission-line stars in NGC2264 (Reipurth+, 2004)J/AJ/127/2228 : VRI photometry of PMS stars in NGC 2264 OB (Makidon+, 2004)J/AJ/128/1684 : NGC 2264: VRIH{alpha} photometry (Sung+, 2004)J/AJ/123/1528 : UBV(RI)_C_ and JHK photometry in NGC 2264 (Rebull+, 2002)J/A+A/355/651 : HRI observations of PMS stars in NGC 2264 (Flaccomio+, 2000)J/A+A/345/521 : BVRI photometry of NGC 2264 (Flaccomio+, 1999)J/AJ/114/2644 : UBVRIHa photometry of NGC2264 (Sung+, 1997)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/741/35https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/741/35http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/741/35https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/741/35https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/741/35http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/741/35GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/741/35/sources (Photometry and polarimetry of point-like sources in the Spokes cluster (NGC 2264))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/741/35/sources?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/741/35/sources?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/741/35/sources?GETtext/xml+votable180.050000true100.31995839.506250.0055555555555555566/236378.650015785639275e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/741/35?format=asciiInfrareddefaultJ/ApJ/741/35/sourcesPhotometry and polarimetry of point-like sources in the Spokes cluster (NGC 2264)SimbadNameSimbad column added by the CDSmeta.idchare_PAH?
