AN is the oldest astronomical journal of the world
that is still being published.

In its renewed appearance it is intended to serve as a supplement in all fields of astrophysical research including instrumentation, numerical methods, solar and stellar astrophysics, extragalactic and cosmological research.
It can be used also for refereed workshop proceedings.

Read more about AN in the press release for its 200th birthday:
Astronomical Notes turns 200.


For a transition period, submission via the old AN submission upload form or even by e-mail attachment is still accepted.

Letter from the Editor

Dear Reader, Dear Author,

volume 342 in 2021 marks the 200th year of the foundation of the Astronomische Nachrichten / Astronomical Notes (AN) and the very first note by H.C. Schumacher in September 1821. To boldly go where no one has gone before, comes to my mind. Business as usual, a today’s astrophysicist could reply but, in any case, reason enough to celebrate. Unfortunately, we are in the middle on a pandemic and celebrating is also done online. We will feature and highlight a forthcoming article in this year’s volume on the history of our journal. Already in its very first volume, then not organized annually but by demand for 1821 to 1823, an article by Carl-Friedrich Gauss on the “Application of the probability calculus to a problem in practical geometry” was introduced and found respectful reception in the community. So, stay tuned for some historical articles in AN in 2021.

The Leibniz-Institute for Astrophysics Potsdam (AIP) continues to host the editorial office in close collaboration with Wiley-VCH GmbH. Last year’s volume of AN featured over 90 peer-reviewed research articles with a total of more than 1000 pages. It again covered a large variety of topics from instrumentation projects and observing campaigns to theoretical studies and numerical simulations. AN’s most recent ISI-Journal Impact Factor is 1.06.

The Covid pandemic in 2020 forced many if not all meeting organizers to cancel their events, and thus also their proceedings. Consequently, only two special issues were edited in 2020, and similar will be the case in 2021. One workshop was “Astrophysics of Hot Plasma in Extended X-ray Sources” organized by the XMM-Newton Science Operations Center which appeared in issue 2 in volume 341. Another one was our own in-house 16th Potsdam Thinkshop on “The rotation periods of cool stars: Measurements, uses, connections and prospects” which took place already in September 2019. It appeared as issue 5 in volume 341 and covered seven review articles.

Finally, AN entered the article open access era as it benefits from a number of agreements Wiley has in place with institutions and funders to help authors publish open access and ensure compliance with open access policies. Authors from an institution affiliated with an open access deal may publish primary research and review articles open access at no charge to the author. Current open access deals exist with institutions from Austria, Finland, Germany, Hungary, Norway, Sweden, The Netherlands, and UK. The effect of these open access initiatives becomes evident in an increased number of open access articles in AN as well as increased usage numbers. However, as a consequence of increasing open access content, our series of free editor’s choice articles will not be continued. A so-called hybrid journal, AN remains a subscription-based journal. Except for open access articles, no page charges are being levied.

Sincerely yours,
Klaus G. Strassmeier, Editor-in-Chief
