cds-question@unistra.frh-ii-regionsyoung-stellar-objectsinfrared-photometryWe investigate the young (proto)stellar population in NGC 2023 and the L 1630 molecular cloud bordering the H II region IC 434, using Spitzer IRAC and MIPS archive data, JCMT SCUBA imaging and spectroscopy as well as targeted BIMA observations of one of the Class 0 protostars, NGC 2023 MM 1. We study the distribution of gas, dust and young stars in this region to see where stars are forming, whether the expansion of the H II region has triggered star formation, and whether dense cold cores have already formed stars. We have performed photometry of all IRAC and MIPS images, and used color-color diagrams to identify and classify all young stars seen within a 22'x26' field along the boundary between IC 434 and L 1630.2009A&A...507.1485Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/507/1485CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/507/1485https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/507/1485http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/507/1485https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/507/1485https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/507/1485http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/507/1485GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/507/1485/sources (Sources detected in mid-IR (table2), near-IR (table3) and MIPS-24{mu}m (table4))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/507/1485/sources?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/507/1485/sources?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/507/1485/sources?GETtext/xml+votable180.050000true85.1637917-2.44605560.0055555555555555566/22854-228556.772611666688002e-21 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/507/1485?format=asciiInfrareddefaultJ/A+A/507/1485/sourcesSources detected in mid-IR (table2), near-IR (table3) and MIPS-24{mu}m (table4)e_Jmag? rms uncertainty on Jmagmagstat.error;phot.mag;em.IR.JfloatnullableHmag? 2MASS H magnitudemagphot.mag;em.IR.Hfloatnullablee_Hmag? rms uncertainty on Hmagmagstat.error;phot.mag;em.IR.HfloatnullableKsmag? 2MASS Ks magnitudemagphot.mag;em.IR.Kfloatnullablee_Ksmag? rms uncertainty on Ksmagmagstat.error;phot.mag;em.IR.KfloatnullableF3.6?
