cds-question@unistra.frsupernovaeinfrared-photometryvisible-astronomybroad-band-photometryIn this paper, we discuss the outcomes of the follow-up campaign of SN 2018ijp, discovered as part of the Zwicky Transient Facility survey for optical transients. Its first spectrum shows similarities to broad-lined Type Ic supernovae around maximum light, whereas later spectra display strong signatures of interaction between rapidly expanding ejecta and a dense H-rich circumstellar medium, coinciding with a second peak in the photometric evolution of the transient. This evolution, along with the results of modeling of the first light-curve peak, suggests a scenario where a stripped star exploded within a dense circumstellar medium. The two main phases in the evolution of the transient could be interpreted as a first phase dominated by radioactive decays, and a later interaction-dominated phase where the ejecta collide with a pre-existing shell. We therefore discuss SN 2018jp within the context of a massive star depleted of its outer layers exploding within a dense H-rich circumstellar medium.2021A&A...650A.174Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/650/A174CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/650/A174https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/650/A174http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/650/A174https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/650/A174https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/650/A174http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/650/A174GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/A+A/650/A174/tableSloan gri (ABMag) photometry of SN 2018ijprecnoRecord number assigned by the VizieR team.
