LaTeX2e class for Astronomy & Astrophysics
(c) EDP Sciences, 2016

The following files are part of the macro package AA

• aa.cls: The document class file

• aa.dem: Example of an article (LaTeX source)

• Directory for BIBTeX style

• aa.bst: Bibliography style file

• natnotes.pdf: Brief reference sheet for Natbib (pdf)
Remember to transfer dvi and pdf files as binaries!

All files are compressed in a single archive:
aa-package.zip

Main changes in the 8.x versions

A&A accepts TeX files designed for LaTeX as well as PDFLaTeX.
Depending on your preferred LaTeX engine (LaTeX or pdfLaTeX), figures should be sent as encapsulated PostScript files or in any other format as PDF, JPG, TIF, BMP, and GIF (compatible with pdfLaTeX).
The new macro does not include the classes traditabstract and structabstract anymore. They are replaced by the command \abstract. See new instructions for details.

The aa class supports now the "e-prints" command with BibTeX.
Two new LaTeX commands, \LEm{a note in the margin} and \LEt{note within the text} have been added.
See the A&A Author's guide on the Web site for more information.

To enable compatibility with 7.x versions, an option has been added. If you don't write structured references (according to to the author-year natbib style), use this option:
\documentclass[bibyear]{aa}

Tips
Contributed by Robert J. Rutten of Utrecht University.

This is a latex recipe to turn the in-text citations into clickers (in xdvi and the pdf or html output file) that link into ADS, opening the corresponding abstract page in the browser. In this manner, an on-screen reader of your paper may open the cited abstract or download the cited paper in parallel to reading your paper, without jumping to the reference list of the latter.

Insert the following commands into the preamble of your latex file:


Usage: use ADS biblabels and enter one per \citeads command, as in:

 The existence of two emission features in the solar spectrum near 12~$\mu$m was announced by \citetads{1981ApJ...247L..97M}. %% Murcray+others, MgI features We explained them long ago \citepads[see][]{1992A&A...253..567C}, %% Carlsson+Rutten+Shchukina MgI using the standard model of the solar atmosphere formulated in the monumental papers by Vernazza et al.\ (\citeyearads{1973ApJ...184..605V}, % VALI \citeyearads{1976ApJS...30....1V}, % VALII \citeyearads{1981ApJS...45..635V}). % VALIII 

This trick was contributed by Robert J. Rutten of Utrecht University. The above example of its usage is taken from his latex manual and template for students at http://www.staff.science.uu.nl/~rutte101/Report_recipe.html

History
The new 2001 Astronomy and Astrophysics journal.
In order to ensure the smoothest transition for both authors and publishers, Springer-Verlag has kindly granted EDP Sciences the permission to use the LaTeX macro package that they developed for A&A Main journal.
Only minor changes have been incorporated between the Springer class (1999) and the EDP Sciences class for the new journal.
- that the abstract is now a command (\abstract{...}) and not an environment, so the \maketitle command has to be placed after the abstract and the keywords
- and that the command \thesaurus does no longer exist.
The journal is now printing using the Postscript TX Times-fonts.
The TX fonts consist of virtual text roman fonts using Adobe Times with some modified and additional text symbols.
The TX fonts are distributed under the GNU public license and are available in the LaTeX distributions since December 2000.
In any case, these fonts and the installation guide are also available in every public TeX archive server, i.e.:
