While very successful and well described, this theory still needs to be revised and fine-tuned to the observations. Our study aims to enlarge the sample of known photometrically variable mCP stars (ACV variables) to pave the way for more robust and significant statistical studies. We derive accurate physical parameters for these objects and discuss our results in the framework of the atomic diffusion theory. We studied 1314 candidate ACV variables that were selected from the Zwicky Transient Factory catalogue of periodic variables based on light curve characteristics. We investigated these objects using photometric criteria, a colour-magnitude diagram, and spectroscopic data from the LAMOST and Gaia missions to confirm their status as ACV variables. Our results confirm that the employed selection process is highly efficient for detecting ACV variables. We have identified 38 stars with v(equ) in excess of 150km/s (with extreme values up to 260km/s). This challenges current theories that cannot explain the occurrence of such fast-rotating mCP stars.2024A&A...687A.211Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/687/A211CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/350 : Gaia EDR3 (Gaia Collaboration, 2020)I/355 : Gaia DR3 Part 1.
