cds-question@unistra.frastrophysical-masersradio-astronomyradio-sourcesWe report the results of a search for 6.7-GHz methanol masers toward low-mass young stellar objects (YSOs) and (pre)protostellar condensations with the Australia Telescope Compact Array (ATCA). Our sample consisted of 13 class 0 protostars and 44 class I YSOs as well as 66 (pre)protostellar condensations. A single detection was obtained toward NGC 2024: FIR4 in the Orion B region. This is the first detection of a 6.7-GHz methanol maser in Orion. The nature of FIR4 has been a subject of debate with some evidence suggesting that it is a very cold high-mass (pre)protostellar condensation and others arguing that it is a low-mass YSO. The discovery of a methanol maser associated with this source is inconsistent with both of these hypotheses and we suggest that FIR4 probably harbours an intermediate- or high-mass YSO.2003A&A...403.1095Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/403/1095CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/134/115 : Medicina 6.7GHz methanol masers survey (Slysh+ 1999)J/A+AS/143/269 : 6.7GHz methanol maser emission survey (Szymczak+, 2000)J/AZh/72/22 : A 95 GHz Survey of Methanol Masers (Valtts+, 1995)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/403/1095https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/403/1095http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/403/1095https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/403/1095https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/403/1095http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/403/1095GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/403/1095/table1 (Source list)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/403/1095/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/403/1095/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/403/1095/table1?GETtext/xml+votable180.050000true79.953561667-5.8680133330.0055555555555555566/21430 21436 22797 22804-22805 22855 22866 22873 29367 29653 36956-36957 37924 39396 42970 42981 42992 44374 47742 47828https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/403/1095?format=asciiRadiodefaultJ/A+A/403/1095/table1Source listrecnoRecord number assigned by the VizieR team.
