# Latex - bibliography style - error

I am using the following packages for bibliography in an article.

\usepackage{amsmath,natbib,wrapfig}


Since the references from my bib file jaarefer was appearing as ? in the pdf file i used the following command.

\renewcommand{\refname}{Bibliography}


My bib style is the following \bibliographystyle{unsrt} \bibliography{jaarefer}

When I compile the tex file with the following content.

"and the dynamical evolution, most of the OCs in general survive only up to a few 100 Myr \citep{PortegiesZwart2010}"


The output in the pdf is the following.

"and the dynamical evolution, most of the OCs in general survive only up to a few 100 Myr[1]. "


I want the the cited reference to occur as the following

"and the dynamical evolution, most of the OCs in general survive only up to a few 100 Myr (PortegiesZwartetal.2010)."


How do I achieve this? The MWE is given below

\documentclass{jaa}

%%suggested packages to be included
\usepackage{graphicx}

%%The following packages are included with the class file.
%%txfonts,balance,textcase,float,amsmath

\usepackage[round]{natbib}

• Welcome to TeX.SX! Please help us help you and add a minimal working example (MWE) that illustrates your problem. Reproducing the problem and finding out what the issue is will be much easier when we see compilable code, starting with \documentclass{...} and ending with \end{document}. – Phelype Oleinik Feb 5 '18 at 13:30
• You will need to use a natbib-compatible style that allows for author-year citations. For lack of an MWE I can't test the ideas offered in tex.stackexchange.com/q/144764/35864. See also jmlr.org/format/natbib.pdf – moewe Feb 5 '18 at 13:37
• @PhelypeOleinik I have added a MWE. – BRMBU Feb 5 '18 at 16:16
• @moewe thanks for the link but it didn't work. Could you please help me out. – BRMBU Feb 5 '18 at 16:16

The class and example file one can download from http://www.ias.ac.in/Journals/Journal_of_Astrophysics_and_Astronomy/Information_for_Authors do not use dedicated bibliography package.

The citations are produced entirely manually in jaaSample.tex

Section text here (Clark \& Caswell 1976; Zwicky 1957).


The bibliography is produced as follows

\begin{theunbibliography}{}
\vspace{-1.5em}

\bibitem{latexcompanion}
Clark D. H., Caswell J. L. 1976, MNRAS, 174, 267
\bibitem{latexcompanion}

\end{theunbibliography}


Note the ridiculous and frankly incorrect use of latexcompanion as a key for all references. But since they don't cite using \cite that does not really matter.

I have never seen the environment theunbibliography, but if its use is required it seems unlikely to me that you could use a standard .bst style without modifications.

Now it becomes even more ... interesting. The class not only defines theunbibliography it also defines thebibliography. Additionally it forces \bibliographystyle{unsrt}. unsrt does not really strike me as a style that works well together with the required author-year citation style.

If you want to submit to this journal my advice would be to create the bibliography and citations manually. That will probably the least hassle, I'm not sure if they can deal with .bbl files or other bibliography packages.

• I use \cite throughout my document. Is there a way that this can be fixed in the tex file or should I just type in the cited references? – BRMBU Feb 6 '18 at 11:02
• @Bryan Well, the document class does not look good. So I'm not sure if they can handle \cite and BibTeX. – moewe Feb 6 '18 at 11:06
• So I'll just go ahead and modify my \cite to just the manes and then type out the references towards the end. – BRMBU Feb 6 '18 at 11:09
• Also I have a problem using the scientific notation \degree and \arcsec. I tried loading the siunitx package but this gives me an error in the document. – BRMBU Feb 6 '18 at 11:11
• @Bryan The thing with siunitx could be a new question. But don't get your hopes up too high. As I say, the class and example document don't make me think that they can support all kinds of TeX packages. – moewe Feb 6 '18 at 11:14
