cds-question@unistra.frmolecular-cloudsextinctionStars form in the cold dense cores of interstellar molecular clouds and the detailed knowledge of the spectrum of masses of such cores is clearly a key for the understanding of the origin of the IMF. To date, observations have presented somewhat contradictory evidence relating to this issue. In this paper we propose to derive the mass function of a complete sample of dense molecular cores in a single cloud employing a robust method that uses uses extinction of background starlight to measure core masses and enables the reliable extension of such measurements to lower masses than previously possible. We use a map of near-infrared extinction in the nearby Pipe dark cloud to identify the population of dense cores in the cloud and measure their masses.2007A&A...462L..17Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/462/L17CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/119/111 : Molecular abundances in dense interstellar clouds (Lee+ 1996)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/462/L17https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/462/L17http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/462/L17https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/462/L17https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/462/L17http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/462/L17GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/462/L17/table1 (Core positions)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/462/L17/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/462/L17/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/462/L17/table1?GETtext/xml+votable180.050000true260.96-30.48060.0055555555555555565/7215 6/28839 28841 28843 28850-28851 28859 28906 29186-29187 29189-29191 29193 29200-29201 29203-29206 29209-29212 29214-29215 29232 29237 29248-29249 29251https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/462/L17?format=asciiOpticaldefaultJ/A+A/462/L17/table1Core positionsSeqCore numbermeta.id;meta.mainintrecnoRecord number assigned by the VizieR team.
