cds-question@unistra.frmagellanic-cloudsbe-starspolarimetryWe present the first detailed imaging polarization observations of six SMC and six LMC clusters, known to have large populations of B-type stars that exhibit excess H{alpha} emission from 2-CD photometric studies, to constrain the evolutionary status of these stars and hence better establish links between the onset of disk formation in classical Be stars and cluster age and/or metallicity. We parameterize and remove the interstellar polarization (ISP) associated with each line of sight, thereby isolating the presence of any intrinsic polarization. We use the wavelength dependence of this intrinsic polarization to discriminate pure gas disk systems, i.e., classical Be stars, from composite gas-plus-dust disk systems, i.e., Herbig Ae/Be or B[e] stars.2007ApJ...671.2040Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/671/2040CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/119/271 : Be stars uvby{beta} photometry (Fabregat+, 1996)J/A+AS/125/75 : UBV photometry of Be stars (Pavlovski+ 1997)J/A+AS/129/289 : Long-term spectrophotometry of Be stars (Moujtahid+ 1998)J/A+AS/134/489 : Be stars in MC young clusters (Keller+ 1999)J/A+A/317/448 : BVRHalpha photometry of NGC 1818 (Grebel 1997)J/A+A/376/144 : BV(RI)_C_H{alpha} photometry of NGC 663 (Pigulski+, 2001)J/other/NewA/9.509 : IRAS observations of Be stars (Zhang+, 2004)J/other/NewA/10.325 : 2MASS observations of Be stars (Zhang+, 2005)J/MNRAS/361/1055 : BVI photometry of LMC Be stars (Sabogal+, 2005)J/ApJ/622/1052 : byH{alpha} photometry of NGC 3766 (McSwain+, 2005)J/A+A/462/683 : Velocities in SMC field of NGC 330 (Martayan+, 2007)J/A+A/472/577 : NGC 330 Be stars and binaries (Martayan+, 2007)J/A+A/478/659 : OGLE Be stars in Galactic Bulge (Sabogal+, 2008)J/ApJ/652/458 : Candidates Be stars BVRHa photometry (Wisniewski+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/671/2040https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/671/2040http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/671/2040https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/671/2040https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/671/2040http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/671/2040GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/671/2040/table13 (IR colors of candidate Be stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/671/2040/table13?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/671/2040/table13?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/671/2040/table13?GETtext/xml+votable180.050000true12.9283333-73.22416670.005555555555555556Cone search capability for table J/ApJ/671/2040/pol (Stars observed in polarimetry)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/671/2040/pol?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/671/2040/pol?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/671/2040/pol?GETtext/xml+votable180.050000true12.9341667-73.24138890.0055555555555555566/33094 33098 33112 33113 33115 33120 33124 33125 33127 33293 33295 33304 33307 33317 33328https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/671/2040?format=asciiOpticaldefaultJ/ApJ/671/2040/pol_dataTotal and intrinsic polarization of candidate Be starsrecnoRecord number assigned by the VizieR team.
