We measure ETGs structural parameters and photometry from Hubble Space Telescope (HST) observations. We use high-quality spectroscopic data from the Multi Unit Spectroscopic Explorer (MUSE) to measure the galaxy central stellar velocity distribution and stellar population properties. With these data, we construct the FP through a robust fitting procedure and analyze its tilt and scatter. We then introduce two hyperplane extensions, one including the stellar mass (M^*^-HP) and another including the stellar-over-total mass fraction (f_e_^*^-HP), and compare their coefficients and scatter to those of the FP. The FP of PLCK G287.0+32.9 is found to have best-fit parameter values consistent with those in the literature (alpha=1.2+/-0.1 and beta=-0.75+/-0.04), with an observed scatter of 0.088dex. The f_e_^*^-HP shows no tilt compared to the theoretical plane (alpha=2.0+/-0.3 and beta=-1.1+/-0.1), with an observed scatter of 0.036dex, and the M^*^-HP reveals an even tighter relation, with an observed scatter of only 0.036. Our findings support the idea that the FP is a lower-dimensional projection of a more complex hyperplane and confirm that the variations in the dark matter content contribute significantly to the tilt of the FP. Future studies incorporating larger samples of galaxies and additional physical parameters may further refine our understanding of the FP and its higher-dimensional extensions.2025A&A...700A.179Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/700/A179CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/686/A4 : Powerful lens galaxy cluster PLCK G287.0+32.9 (D'Addona+, 2024)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/700/A179https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/700/A179http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/700/A179https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/700/A179https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/700/A179http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/700/A179GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/700/A179/tablea1 (Parameters of the secure ETG sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/700/A179/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/700/A179/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/700/A179/tablea1?GETtext/xml+votable180.050000true177.7235042241437-28.097370985970.0055555555555555566/247352.0401237512456292e-19 2.706461185444514e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/700/A179?format=asciiOpticalInfrareddefaultJ/A+A/700/A179/tablea1Parameters of the secure ETG samplerecnoRecord number assigned by the VizieR team.
