Observational evidence has been obtained for a handful of systems in outburst over the last two decades. We present the results of a systematic study searching for spiral density waves in CVs, and report their detection in two of the sixteen observed systems. While most of the systems observed present asymmetric, non-Keplerian accretion discs during outburst, the presence of ordered structures interpreted as spiral density waves is not as ubiquitous as previously anticipated. From a comparison of systems by their system parameters it appears that inclination of the systems may play a major role, favouring the visibility and/or detection of spiral waves in systems seen at high inclination.2020MNRAS.491.2217Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/491/2217CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/491/2217https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/491/2217http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/491/2217https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/491/2217https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/491/2217http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/491/2217GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/491/2217/table3 (Classification and coordinates of the observed systems)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/491/2217/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/491/2217/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/491/2217/table3?GETtext/xml+votable180.050000true270.593545.87902780.005555555555555556Cone search capability for table J/MNRAS/491/2217/table5 (System parameters of the systems with detected spiral structures)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/491/2217/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/491/2217/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/491/2217/table5?GETtext/xml+votable180.050000true350.785567518.41644640.0055555555555555566/353 2440 2659 3029 4790 6086 8281 8977 9238 10232 11084 12859 12933 14018 14529 14701 15035-15036 15105 16046 19076 19297 20066 22321 26157 26446 29217 30597 31520 31852 39459 45927 475252.85864675833786e-19 3.5010283109654867e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/491/2217?format=asciiUVOpticaldefaultJ/MNRAS/491/2217/table3Classification and coordinates of the observed systemsSimbadNameSimbad column added by the CDSmeta.idcharnullablerecnoRecord number assigned by the VizieR team.
