Hi Rainer,

sorry for the late answer.
You are right, it would be much more elegant to have 'Astrophysical Journal' than 'apj' in the bibliography.
I found the sty file
http://cdsads.u-strasbg.fr/abs_doc/aas_macros.sty
with all of the definitions, and I include it in the preamble
(\documentclass[12pt,aas_macros]{book}), but it does not have any effect, it still gives the same error.
Putting the aas_macros into the option list is the only change I've made to the source tex file.
Am I doing something wrong?
Thanks!

Joseph

Style files cannot be loaded via class option. They have to be loaded by \usepackage. So you have to use

Code: [Select all] [Expand/Collapse] [Download] ({untitled.tex}) Open in Overleaf

\documentclass[12pt]{book}
\usepackage{aas_macros}
