Since its introduction in 1976 by Hans-Michael Maitzen, the Δa system has not only been successfully applied to the classical chemically peculiar stars of the upper main sequence, but also to galactic and extragalactic star clusters. New possible applications for studying galaxies, quasars and other astrophysical objects of interest are discussed.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Ernst Pauzen\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 3736972830\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9783736972834\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Cuvillier\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 12\/30\/2020\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 248\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.66lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 8.27h x 5.83w x 0.52d","brand":"Ernst Pauzen","offers":[{"title":"Paperback","offer_id":48446310482175,"sku":"9783736972834","price":81.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_f1a94190-c966-446c-af36-df3577a0fc87.jpg?v=1777223843","url":"https:\/\/www.whiterainbookhouse.com\/products\/the-a-photometric-system-ernst-pauzen-9783736972834","provider":"WR Book House","version":"1.0","type":"link"}
