Deep images taken as part of the POPIPlaN survey indicate that the nebula may possess a bipolar morphology similar to other post-common-envelope planetary nebulae. Simultaneous light and radial velocity curve modelling reveals the newly discovered binary system to comprise a highly-irradiated, M-type main-sequence star in a 5.9 hour orbit with a hot pre-white-dwarf. The nebular progenitor is found to have a particularly low mass of around 0.4M_{sun}_, making PN G283.7-05.1 one of only a handful of candidate planetary nebulae to be the product of a common-envelope event while still on the red giant branch. Beyond its low mass, the model temperature, surface gravity and luminosity are all found to be consistent with the observed stellar and nebular spectra through comparison with model atmospheres and photoionisation modelling. However, the high temperature (Teff~95kK) and high luminosity of the central star of the nebula are not consistent with post-RGB evolutionary tracks.2020A&A...642A.108Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/642/A108CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/642/A108https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/642/A108http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/642/A108https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/642/A108https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/642/A108http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/642/A108GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/A+A/642/A108/bbandB-band photometry of the central star of PN G283.7-05.1recnoRecord number assigned by the VizieR team.
