cds-question@unistra.fryoung-stellar-objectsinfrared-photometryThe Cygnus-X star-forming complex is one of the most active regions of low- and high-mass star formation within 2kpc of the Sun. Using mid-infrared photometry from the IRAC and MIPS Spitzer Cygnus-X Legacy Survey, we have identified over 1800 protostar candidates. We compare the protostellar luminosity functions of two regions within Cygnus-X: CygX-South and CygX-North. These two clouds show distinctly different morphologies suggestive of dissimilar star-forming environments. We find the luminosity functions of these two regions are statistically different. Furthermore, we compare the luminosity functions of protostars found in regions of high and low stellar density within Cygnus-X and find that the luminosity function in regions of high stellar density is biased to higher luminosities. In total, these observations provide further evidence that the luminosities of protostars depend on their natal environment. We discuss the implications this dependence has for the star formation process.2014AJ....148...11Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/148/11CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/316 : UKIDSS-DR6 Galactic Plane Survey (Lucas+ 2012)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)J/AJ/144/31 : Spitzer+2MASS photometry of protostar candidatesJ/A+A/543/A101 : OB stars in Cygnus OB2 association (Comeron+, 2012)J/ApJ/720/679 : Optical spectroscopy in Cygnus X region (Beerer+, 2010)J/A+A/375/539 : JHK photometry of HII regions in Cyg X (Comeron+, 2001)J/A+A/241/551 : Radio continuum in Cygnus X region (Wendker+ 1991)http://irsa.ipac.caltech.edu/data/SPITZER/Cygnus-X/ : Cygnus-X Spitzer Legacyhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/148/11https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/148/11http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/148/11https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/148/11https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/148/11http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/148/11GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/148/11/table3 (Properties of protostar candidates in Cygnus-X)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/148/11/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/148/11/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/148/11/table3?GETtext/xml+votable180.050000true304.041542.08368890.0055555555555555565/3655 3661 3666 3667 3670 3672 3673 3674 6/14652 14653 14659 14662 14663 14686 14700 14704 14705 147066.772611666688002e-21 6.185923063528282e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/148/11?format=asciiInfrareddefaultJ/AJ/148/11/table3Properties of protostar candidates in Cygnus-XrecnoRecord number assigned by the VizieR team.
