|Open Access Policy|
Astronomy & Astrophysics (A&A) and EDP Sciences are in favor of broad and easy access to all published scientific information and have taken numerous steps in this direction, with the different services listed below:
Green Open Access
The Publisher and A&A encourage arXiv archiving or self-archiving of the final PDF file of the article exactly as published in the journal and without any period of embargo.
Sections in Full Open Access
All Letters to the Editor and all articles published in the online sections (Atomic, molecular, and nuclear data - Astronomical instrumentation - Catalogs and data - Numerical methods and codes) are in full (gold) open access at no cost to the authors.
Archives in Free Access
All articles published in the other sections of the Journal become freely accessible 12 months after publication.
Open Access Option
Authors can pay a promotional fee of 400 euros to make their online article perpetually, universally, and freely accessible (gold open access). The fee covers only a fraction of the editorial and production costs.
Latest articles FREE
This service allows non-subscribers to the journal to gain free access to the full online edition of the most recent articles of A&A on the EDP Sciences website. The Latest articles FREE service requires registration and is meant to be used by individuals for their private studies or scholarly research, and not for commercial benefit.
