cds-question@unistra.fra-starsinterstellar-mediumQuantifying the composition of the material in protoplanetary disks is paramount to determining the potential for exoplanetary systems to produce and support habitable environments. When considering potential habitability, complex organic molecules are of relevance, key among which is methanol (CH_3_OH). Methanol primarily forms at low temperatures via the hydrogenation of CO ice on the surface of icy dust grains and is a necessary basis for the formation of more complex species such as amino acids and proteins. We report the detection of CH_3_OH in a disk around a young, luminous A-type star, HD 100546. This disk is warm and therefore does not host an abundant reservoir of CO ice. We argue that the CH_3_OH cannot form in situ, and hence this disk has probably inherited complex-organic-molecule-rich ice from an earlier cold dark cloud phase. This is strong evidence that at least some interstellar organic material survives the disk formation process and can then be incorporated into forming planets, moons and comets. Therefore, crucial pre-biotic chemical evolution already takes place in dark star-forming clouds.2021NatAs...5..684Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/NatAs/5.684CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/592/A83 : HD 100546 and TW Hya model abundances (Kama+, 2016)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/NatAs/5.684https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/NatAs/5.684http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/NatAs/5.684https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/NatAs/5.684https://vizier.iucaa.in/viz-bin/votable?-source=J/other/NatAs/5.684http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/NatAs/5.684GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/NatAs/5.684/list (List of fits datacubes)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/NatAs/5.684/list?https://vizier.iucaa.in/viz-bin/conesearch/J/other/NatAs/5.684/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/NatAs/5.684/list?GETtext/xml+votable180.050000true173.35538-70.19480.0055555555555555566/37186https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/NatAs/5.684?format=asciidefaultJ/other/NatAs/5.684/listList of fits datacubesrecnoRecord number assigned by the VizieR team.
