cds-question@unistra.frstellar-associationsg-starsThe earliest evolutionary stages of low-mass protostars are characterised by the so-called hot-corino stage, when the newly born star heats the surrounding material and enrich the gas chemically. Studying this evolutionary phase of solar protostars may help understand the evolution of prebiotic complex molecules in the development of planetary systems. In this paper we focus on the occurrence of glycolaldehyde (HCOCH_2_OH) in young solar analogs by performing the first homogeneous and unbiased study of this molecule in the Class 0 protostars of the nearby Perseus star forming region. We obtained sub-arcsec angular resolution maps at 1.3mm and 1.4mm of glycolaldehyde emission lines using the IRAM Plateau de Bure (PdB) interferometer in the framework of the CALYPSO IRAM large program.2017A&A...599A.121Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/599/A121CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/599/A121https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/599/A121http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/599/A121https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/599/A121https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/599/A121http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/599/A121GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/599/A121/list (List of fits files)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/599/A121/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/599/A121/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/599/A121/list?GETtext/xml+votable180.050000true52.2315431.24360.0055555555555555566/862https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/599/A121?format=asciidefaultJ/A+A/599/A121/listList of fits filesRAJ2000Right Ascension of center (J2000)degpos.eq.ra;meta.mainrecnoRecord number assigned by the VizieR team.
