cds-question@unistra.frh-ii-regionsinfrared-photometryUsing H{alpha} grism spectroscopy and optical and Two-Micron All-Sky Survey photometry of the fields containing NGC 1893 and two emission nebulae, Sim 129 and Sim 130, we show the presence of a number of H{alpha} and near-infrared excess sources towards the region between HD 242935 and the two emission nebulae. Among them a large majority of these pre-main-sequence candidate sources are concentrated towards regions closer to Sim 129 and Sim 130.2007MNRAS.379.1237Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/379/1237CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/379/1237https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/379/1237http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/379/1237https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/379/1237https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/379/1237http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/379/1237GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/379/1237/table1 (*Our optical and 2MASS NIR results for the 49 sources are presented.)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/379/1237/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/379/1237/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/379/1237/table1?GETtext/xml+votable180.050000true80.77833.47780.0055555555555555566/12871.5062136169708525e-19 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/379/1237?format=asciiInfrareddefaultJ/MNRAS/379/1237/table1*Our optical and 2MASS NIR results for the 49 sources are presented.recnoRecord number assigned by the VizieR team.
