How to remove the line “Received; acceped” from title?

Question

I am using the aastex.lyx template to write an article and I cannot find a way to remove the "Received; -------- Accepted" line coming after the title. Does anyone know how to remove it ?

Answer 1

Looking into aastex.cls, the macro responsible for typesetting "Received/Accepted" is \@dates with the following definition:

\def\@dates{\ifx\@title\@empty\else {Received}\space%
 \ifx\@empty\@recvdate\@rcvaccrule\else\@recvdate\fi;%
 \hspace{1.5em}{accepted}\space%
 \ifx\@empty\@accptdate\@rcvaccrule\else\@accptdate\fi%
\fi}%                                                 %

Disabling \@dates seems to do the trick.

\documentclass{aastex}

\makeatletter
\let\@dates\relax
\makeatother

\begin{document}

\author{(Author)}
\title{(Title)}
\maketitle

\end{document}

As you're using LyX, you have to add the code lines from \makeatletter to \makeatother into your LaTeX preamble.
