We perform mode identification for five $\delta$ Scuti stars in the Pleiades star cluster, using custom light curves from K2 photometry. By creating \'echelle diagrams, we identify radial and dipole ridges, comprising a total of 28 16 modes across stars. also suggest possible identities those that lie offset ridges. calculate non-rotating stellar pulsation models to verify our identifications, finding good agreement within age metallicity constraints cluster. find all stars, least dense are preferred, reflecting lower density these oblate, rotating Three show rotationally-split multiplets. conclude sample shows promise asteroseismic rotation rates, masses, ages with future. Our preliminary modelling indicates some sensitivity helium abundance.
