2MASS observations of Be stars J/other/NewA/10. ivo://CDS.VizieR/J/other/NewA/10.325 CDS Zhang P. Chen P.S. Yang H.T. 2006-09-10T13:11:04Z 2006-09-10T13:07:23Z CDS support team CDS, Observatoire de Strasbourg, 11 rue de l'Universite, F-67000 Strasbourg, France cds-question@unistra.fr emission-line-stars be-stars infrared-photometry A catalogue of almost all known Galactic Be stars in the 2MASS (<II/246>) database (1185 in total) and in the MSX (<V/114>) database (225 in total) is presented in this paper. From the color-color diagrams and spectral indexes, it is found that the IR excesses for many samples are due to free-free and free-bound emission from the ionized material around a Be star as suggested previously and that the mean spectral index derived for the samples is 1.50+/-0.34 between J to K bands and 1.14+/-0.42 between K to A bands, respectively. However, it is also found that there are eight Be stars that have large near infrared excess emission with spectral index values outside the range expected for freefree and freebound emission. This is likely attributed to circumstellar dust emission. 2005NewA...10..325Z https://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/NewA/10.325 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to III/67 : Catalogue of Be stars (Jaschek+, 1982) II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003) V/114 : MSX6C Infrared Point Source Catalog (Egan+ 2003) https://cds.unistra.fr/vizier-org/licences_vizier.html https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/NewA/10.325 https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/NewA/10.325 http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/NewA/10.325 https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/NewA/10.325 https://vizier.iucaa.in/viz-bin/votable?-source=J/other/NewA/10.325 http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/NewA/10.325 GET text/xml+votable https://tapvizier.cds.unistra.fr/TAPVizieR/tap Cone search capability for table J/other/NewA/10.325/table1 (2MASS associations of Be stars) https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/NewA/10.325/table1? https://vizier.iucaa.in/viz-bin/conesearch/J/other/NewA/10.325/table1? http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/NewA/10.325/table1?
