I am having trouble running this Example of a manuscript header with structured abstract which the journal of Astronomy and Astrophysics provides on their webpage. I have downloaded the "A&A LaTeX macro package" which they provide on their website, and put all files into the document folder.

When I copy-paste the above example into a tex-file, and try to typeset, I first get an error that there would be too many }. After deleting the one which looks too much I get the error/message:


Class aa Warning: The running head built automatically from \author and \titlee xceeds the pagewidth, please supply a shorter form with \authorrunning and/or \titlerunning prior to \maketitle on input line 48.


(\usr/local/texlive/2019/texmf-dist/tex/latex/txfonts/t1txtt.fd)) *

I am not sure what that means, and I did not find anything relevant when googling for that error message. Any suggestions?

    The message seems to be a warning (and not an error), suggesting that you use the \authorrunning and/or \titlerunning commands to supply a shorter form of the authors and/or title, that will fit in the page header.

  • @Marijn Thanks for the reply! Yes, I suppose you are right, thanks! I now found another way to get a template compiled: Their macro package contains a file named aa.dem. I guess .dem stands for demonstration, since it is basically an example template code. Renaming this file to .tex dies the trick, and it compiles straight away.

Just to be more clear on what @Marijn answered. \authorrruunning{} and \titlerunning{} commands have to be included right before \maketitle. This is explained in the A&A accueil page.

\titlerunning{short title}
\authorrunning{name(s) of author(s)}
