We find no evidence of stripped companion emission in any of the nebular-phase spectra. Upper limits are placed on the amount of mass that could go undetected in each spectrum using recent hydrodynamic simulations. With these null detections, we place an observational 3{sigma} upper limit on the fraction of SNe Ia that are produced through the classical H-rich non-degenerate companion scenario of <5.5 per cent. Additionally, we set a tentative 3{sigma} upper limit on He star progenitor scenarios of <6.4 per cent, although further theoretical modelling is required. These limits refer to our most representative sample including normal, 91bg-like, 91T-like, and 'super-Chandrasekhar' SNe Ia but excluding SNe Iax and SNe Ia-CSM. As part of our analysis, we also derive a Nebular Phase Phillips Relation, which approximates the brightness of an SN Ia from 150 to 500d after maximum using the peak magnitude and decline rate parameter {Delta}m_15_(B).2020MNRAS.493.1044Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/493/1044CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/493/1044https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/493/1044http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/493/1044https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/493/1044https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/493/1044http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/493/1044GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/493/1044/tableb2 (All SNe Ia studied in this work)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/493/1044/tableb2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/493/1044/tableb2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/493/1044/tableb2?GETtext/xml+votable180.050000true27.6717917-14.51798610.0055555555555555566/11 611 697 2265 2790 4149 4447 4521 4719 5975 6178 7241 7606 8256 8667 10501 11246 11280 11434 11496 12025 12455 13907 13925 16322 16537 17340 17429 17741 17761 17912 18011 18061 18209 18324-18325 18830 18854 19777 20601 20677 21239 21300 22650 23077 24920 24926 24957 25353 25571 25912 25960 26271 26309 26336 26355 26500 27367 27426 27512 27738 27773 27918 28035 28294 28299 31158 31230 31522 32620 32797 34361 34493 34531 34534 34540 34884 35885 36045 36139 36287 36391 36639 37305 37429 37579 38655 38664 38730 38868 38956 39677 40379 40424 43262 43339 43626 43630 43873-43874 44000 44915 46104 46439 46985 47262 47542https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/493/1044?format=asciiOpticalInfrareddefaultJ/MNRAS/493/1044/tableb2All SNe Ia studied in this workSimbadNameSimbad column added by the CDSmeta.idcharnullablerecnoRecord number assigned by the VizieR team.
