cds-question@unistra.frinfrared-sourcesinterstellar-mediumprotostarsWe present far-infrared observations of Monoceros R2 (a giant molecular cloud at approximately 830pc distance, containing several sites of active star formation), as observed at 70um, 160um, 250um, 350um, and 500um by the PACS and SPIRE instruments on the Herschel Space Observatory as part of the HOBYS Key programme. The Herschel data are complemented by SCUBA-2 data in the submillimetre range, and WISE and Spitzer data in the mid-infrared. In addition, C^18^O data from the IRAM 30-m Telescope are presented, and used for kinematic information. Sources were extracted from the maps with getsources, and from the fluxes measured, spectral energy distributions were constructed, allowing measurements of source mass and dust temperature. Of 177 Herschel sources robustly detected in the region (a detection with high signal-to-noise and low axis ratio at multiple wavelengths), including protostars and starless cores, 29 are found in a filamentary hub at the centre of the region (a little over 1% of the observed area). These objects are on average smaller, more massive, and more luminous than those in the surrounding regions (which together suggest that they are at a later stage of evolution), a result that cannot be explained entirely by selection effects. These results suggest a picture in which the hub may have begun star formation at a point significantly earlier than the outer regions, possibly forming as a result of feedback from earlier star formation. Furthermore, the hub may be sustaining its star formation by accreting material from the surrounding filaments.2017A&A...607A..22Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/607/A22CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/607/A22https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/607/A22http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/607/A22https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/607/A22https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/607/A22http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/607/A22GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/607/A22/monr2cat (Fluxes and information for the 177 sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/607/A22/monr2cat?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/607/A22/monr2cat?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/607/A22/monr2cat?GETtext/xml+votable180.050000true91.9178-6.413030.0055555555555555566/21445 21447 21458https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/607/A22?format=asciiInfrareddefaultJ/A+A/607/A22/monr2catFluxes and information for the 177 sourcesTypeSource typesrc.classcharrecnoRecord number assigned by the VizieR team.
