Constraining the accretion history of individual protostars is therefore an important aspect of star formation research. The goal of the study presented here is to determine whether high-mass (proto)stars gain their mass from a compact (<0.1pc) fixed-mass reservoir of gas, often referred to as dense cores, in which they are embedded, or whether the mass growth of high-mass stars is governed by the dynamical evolution of the parsec-scale clump that typically surrounds them. To achieve this goal, we performed a 350micron continuum mapping of 11 infrared dark clouds, along side some of their neighbouring clumps, with the ArTeMiS camera on APEX. By identifying about 200 compact ArTeMiS sources, and matching them with Herschel Hi-GAL 70micron sources, we have been able to produce mass vs. temperature diagrams. We compare the nature (i.e. starless or protostellar) and location of the ArTeMiS sources in these diagrams with modelled evolutionary tracks of both core-fed and clump-fed accretion scenarios. We argue that the latter provide a better agreement with the observed distribution of high-mass star-forming cores. However, a robust and definitive conclusion on the question of the accretion history of high-mass stars requires larger number statistics.2020MNRAS.496.3482Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/496/3482CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/565/A75 : ATLASGAL: dust condensations in Galactic planeJ/MNRAS/471/100 : Hi-GAL compact source catalog. -71.0<l<67.0 (Elia+, 2017)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/496/3482https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/496/3482http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/496/3482https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/496/3482https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/496/3482http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/496/3482GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/496/3482/table2 (Properties of the 203 ArTeMiS compact sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/496/3482/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/496/3482/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/496/3482/table2?GETtext/xml+votable180.050000true236.587134-54.1791490.0055555555555555566/41813-41814 41817 41820 42376 42390 42392 42496https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/496/3482?format=asciiInfraredMillimeterdefaultJ/MNRAS/496/3482/table2Properties of the 203 ArTeMiS compact sourcesrecnoRecord number assigned by the VizieR team.
