Using the scaling relations, it is possible to estimate masses and radii for solar-type pulsators. However, these stars are not the only kind of stellar objects that follow these rules: <jats:italic>\u03b4<\/jats:italic> Scuti stars seem to be characterized with seismic indexes such as the large separation (\u0394<jats:italic>\u03bd<\/jats:italic>). Thanks to long-duration high-cadence TESS light curves, we analysed more than two thousand of this kind of classical pulsators. In that way, we propose the frequency at maximum power (<jats:italic>\u03bd<\/jats:italic><jats:sub>max<\/jats:sub>) as a proper seismic index since it is directly related with the intrinsic temperature, mass and radius of the star. This parameter seems not to be affected by rotation, inclination, extinction or resonances, with the exception of the evolution of the stellar parameters. Furthermore, we can constrain rotation and inclination using the departure of temperature produced by the gravity-darkening effect. This is especially feasible for fast rotators as most of <jats:italic>\u03b4<\/jats:italic> Scuti stars seem to be.<\/jats:p>","DOI":"10.1051\/0004-6361\/201937262","type":"journal-article","created":{"date-parts":[[2020,5,1]],"date-time":"2020-05-01T18:47:18Z","timestamp":1588358838000},"page":"A59","source":"Crossref","is-referenced-by-count":33,"title":["Unveiling the power spectra of <i>\u03b4<\/i> Scuti stars with TESS"],"prefix":"10.1051","volume":"638","author":[{"given":"S.","family":"Barcel\u00f3 Forteza","sequence":"first","affiliation":[]},{"given":"A.","family":"Moya","sequence":"additional","affiliation":[]},{"given":"D.","family":"Barrado","sequence":"additional","affiliation":[]},{"given":"E.","family":"Solano","sequence":"additional","affiliation":[]},{"given":"S.","family":"Mart\u00edn-Ruiz","sequence":"additional","affiliation":[]},{"given":"J.
