Author Guideline

This is the guideline for the preparation and submission of manuscripts to the Journal of the Korean Astronomical Society (hereafter JKAS). This guideline may be revised without notice. For submitting a paper, please contact the JKAS Editorial Office (jkas@astro.snu.ac.kr).


1. Scope and Ethics Policy

A. General

JKAS is an international scientific journal publishing papers in all fields of astronomy and astrophysics. All manuscripts are subject to the scrutiny of referees. Manuscripts submitted to JKAS must comply with the ethics policy of JKAS. Six regular issues are published each year on February 28, April 30, June 30, August 31, October 31, and December 31. One year's issues compose one volume.


B. Classification of manuscripts

Manuscripts are classified into Research Papers, Rapid Communications, and Reviews. Footnotes to article titles may be used to indicate Rapid Communications and Reviews when they are published in JKAS.

Research Papers reporting original work constitute the main part of JKAS. They should contain new and scientifically significant results that have not been previously published.

Rapid Communications are concise research papers that are published on a fast track. Rapid Communications are limited to approximately 4 pages in length.

Reviews deliver comprehensive summaries of recent advances in any of the fields of major interest. Review papers may be solicited either by invitation or by approval of the editorial board. Any individual author may send a letter of intent seeking approval to the editor-in-chief before preparing the manuscript.


C. Ethics policy

All authors must conform to the JKAS Ethics Policy. JKAS examines all articles submitted for publication for signs of plagiarism using third-party software. Authors who submit an article that had previously been submitted to another journal have to declare this fact upon submission of their work to JKAS. Authors who notice a serious error in their work after publication should inform the JKAS Editorial Office and prepare an Erratum, or request retraction of their work, as soon as possible. Authors and referees are required to declare any conflict of interest relevant to the work under consideration.



2. Preparing a Manuscript

A. Language

The manuscript should be written clearly and concisely in English. Those who are not good at English writing are encouraged to get assistance from others before submission. Manuscripts written in poor English can be declined by the scientific editors without refereeing.


B. Structure

The manuscript should contain title, author(s), abstract, key words, main body, acknowledgements, and references. Key words should be taken from the international list of astronomy journal key words. The main body consists of text, figures, and tables. All figures, tables, and references should be cited in the text.


C. Figures

When a paper is compiled using standard LaTeX (which is assumed to be the default), each figure should be provided as a single Encapsulated PostScript (EPS) file. Alternatively, article PDFs may be generated directly from the source file(s) using PDFLaTeX; in this case, each figure must be a single PDF, PNG, or JPG file. (Postscript files do not work with PDFLaTeX.)

Vector graphics (EPS, PDF) are strongly preferred over raster graphics (PNG, JPG) because they can be scaled arbitrarily. For raster graphics, the resolution should be approximately 300 dpi, corresponding to about 1000 pixels along the horizontal axis for figures spanning across a single column and to about 2000 pixels along the horizontal axis for figures spanning across a full page.

Figures must be of high quality. All lines, symbols, and labels must be clearly visible when the figure is scaled to publication size. In general, annotations and axis labels should at least have approximately the same size as the text of the figure caption. We strongly encourage authors to create figures that are accessible to readers with impaired eyesight or color blindness.

All figures should be referred to in the text and should be arranged properly. A descriptive legend (caption) should be provided for each figure.

D. Tables, section titles, in-text references, and bibliography

Tables should be coded with LaTeX. Each table should be given a title and descriptive heading. Notes and the units of the quantities listed can be given below the table.

All (sub)section titles should be written with the first letter of each word being capitalized, except of articles, prepositions, and conjunctions. (Else than in previous versions of the JKAS style, article and section titles are not capitalized any more; instead, they are now set in small caps.)

The bibliography should include only works referred to in the text. References should be listed at the end of the paper in alphabetical order under the first author's name. Multiple references to the same author or team of authors should be in chronological order. Multiple references to the same author in the same year should be distinguished by adding a, b, c, etc. to the publication year. References should contain the names and initials of the first three authors followed by "et al."; year; paper title; journal acronym; volume number; first page.


3. Submitting a Manuscript

A. First and revised submissions before acceptance

The manuscript should be submitted electronically to the JKAS Office through the online submission system or by email (jkas@astro.snu.ac.kr). The Editorial Office will send a confirmation message with an article ID number. If you do not receive such a message within one week, please contact the Editorial Office. A single processed document file in PDF format is needed for the initial review. The author who first submits the manuscript is usually considered to be the corresponding author, and is in charge of all correspondence thereafter, unless the authors specify a different corresponding author.


B. Final submission after acceptance

After the manuscript is accepted, the authors are requested to submit the original LaTeX manuscript file and figure files prepared in encapsulated postscript format. Tables should be included into the manuscript file. This final version needs to contain exactly the same content as the accepted version.


C. Preprints and databases

We strongly encourage authors to upload their final manuscript to the arXiv preprint server to ensure wide distribution of their work. All JKAS papers are added to the SAO/NASA Astrophysics Data System after publication.



4. Publication, page charge, reprints, and proofs

A. Publication agreement, page charges

Upon request by the editorial office of JKAS, the authors of the accepted manuscript should return the filled and signed Publication Agreement. JKAS is published under Creative Commons license CC BY-SA 4.0; this means that others may freely use and share work published in JKAS as long as they do not make modifications without noting them as such.

Page charges are subject to change without notice. For articles submitted from September 1, 2019, onward, page charges are 70,000 KRW per black-and-white page and 140,000 KRW per printed color page. (For articles submitted until August 31, 2019, the page charges are 50,000 KRW and 100,000 KRW, respectively.) The on-line edition is in color, color print is optional. Authors who cannot afford the page charges are encouraged to apply for a page charge exemption when submitting their article to JKAS.


B. Proofs

The authors should return page proofs within two business days of their receipt. Corrections that affect the scientific content of the manuscript will be referred to the Editor-in-Chief for decision. Authors are liable for the cost of alterations of the original composition.
