The use case requires the identification of variable stars of the Cepheid class and the determination of the relation between their period and their intrinsic luminosity.http://vo-for-education.oats.inaf.it/eng_download.htmlGeneralCitesAladinThe AIDA M31 tutorial is licensed under the `Creative Commons Attribution 4.0 License <http://creativecommons.org/licenses/by/4.0/>`_ .. image:: /static/img/ccby.png :alt: [CC-BY] https://vo-for-education.oats.inaf.it/use_cases/en_aida_07_andromeda.pdfhttp://svn.ari.uni-heidelberg.de/svn/edu/trunk/aida_07_andromeda/en/en_aida_07_andromeda.odtenhttps://vo-for-education.oats.inaf.it/use_cases/it_aida_07_andromeda.pdfhttp://svn.ari.uni-heidelberg.de/svn/edu/trunk/aida_07_andromeda/it/it_aida_07_andromeda.odtitDistanza della Galassia di Andromedahttps://vo-for-education.oats.inaf.it/use_cases/de_aida_07_andromeda.pdfdeWie weit ist die Andromeda-Galaxie entfernt?https://vo-for-education.oats.inaf.it/use_cases/es_aida_07_andromeda.pdfesDistancia a Andrómedahttps://vo-for-education.oats.inaf.it/use_cases/fr_aida_07_andromeda.pdffrMesurer la distance d’Andromèdehttps://sundai.sakura.ne.jp/VOstudy/Andromeda.htmljpはじめに
