Astronomy & Astrophysics is an international Journal which publishes papers on all aspects of astronomy and astrophysics (theoretical, observational, and instrumental) independently of the techniques used to obtain the results.
The journal is published by EDP Sciences. A paper edition is produced as well as a parallel electronic (on-line) edition.
Institutions and private individuals can subscribe to A&A.
Access to the on-line version of the journal is defined by IP number. Access is free to subscribers of the journal. A username and password are not required.
Part of the material accepted for publication will be published only in electronic form. This holds, in general, for larger appendices, large amounts of similar figures, large tables, and the like. That material is, however, an integral part of the on-line publication and is included in each electronic download.
An archive of the on-line edition and of the tabular material only published in electronic form is maintained by the Centre des Donnes Stellaires (CDS) in Strasbourg.
Astronomy & Astrophysics is a journal established through the amalgamation of various national journals. New Member-Countries can be admitted upon fulfilling certain criteria.
The journal is governed by the Board of Directors, whose members are designated by the Member Countries. The Board decides on the policies for A&A which include the general guidelines for publishing, the selection of the Editors, the various financial aspects, as well as the membership of countries.
