We review the PLRs in the recent literature, and add a new inference from a large sample of \u03b4 Sct. We highlight the difficulty in identifying the fundamental mode and show that rotation-induced surface effects can impact the measured luminosities, explaining the broadening of the PLR. We derive a tight relation between the low-order large separation and the fundamental radial mode frequency (F0) that holds for rotating stars, thus paving the way towards mode identification. We show that the PLRs we obtain for different samples are compatible with each other and with the recent literature, and with most observed \u03b4 Sct stars when taking rotation effects into account. We also find that the highest-amplitude peak in the frequency spectrum corresponds to the fundamental modein most \u03b4 Sct, thus shedding some light on their elusive mode selection mechanism.<\/jats:p>","DOI":"10.1017\/s1743921323003368","type":"journal-article","created":{"date-parts":[[2024,2,6]],"date-time":"2024-02-06T09:12:52Z","timestamp":1707210772000},"page":"239-249","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":1,"title":["The PL diagram for \u03b4 Sct stars: back in business as distance estimators"],"prefix":"10.1017","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6906-4526","authenticated-orcid":false,"given":"Antonio","family":"Garca Hern\u00e1ndez","sequence":"first","affiliation":[]},{"given":"Javier","family":"Pascual-Granado","sequence":"additional","affiliation":[]},{"given":"Mariel","family":"Lares-Martiz","sequence":"additional","affiliation":[]},{"given":"Giovanni M.","family":"Mirouh","sequence":"additional","affiliation":[]},{"given":"Juan Carlos","family":"Su\u00e1rez","sequence":"additional","affiliation":[]},{"given":"Sebasti\u00e1","family":"Barcel\u00f3 Forteza","sequence":"additional","affiliation":[]},{"given":"Andr\u00e9s","family":"Moya","sequence":"additional","affiliation":[]}],"member":"56","published-online":{"date-parts":[[2024,2,6]]},"container-title":["Proceedings of the International Astronomical Union"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S1743921323003368","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,10,17]],"date-time":"2024-10-17T05:52:25Z","timestamp":1729144345000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S1743921323003368\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,12]]},"references-count":0,"journal-issue":{"issue":"S376","published-print":{"date-parts":[[2022,12]]}},"alternative-id":["S1743921323003368"],"URL":"https:\/\/doi.org\/10.1017\/s1743921323003368","relation":{},"ISSN":["1743-9213","1743-9221"],"issn-type":[{"type":"print","value":"1743-9213"},{"type":"electronic","value":"1743-9221"}],"subject":[],"published":{"date-parts":[[2022,12]]},"assertion":[{"value":"\u00a9 The Author(s), 2024.
