Submission guidelines

Planetary Research strives to make the publication process as painless as possible, not only for our authors, but also for our editors, reviewers, and journal staff. For this reason, the journal performs a rigorous quality control on new manuscripts. When submissions do not respect the journal's submission guidelines, they will be systematically declined and will not be forwarded to the editorial board.

Authors should experience few problems if they respect the following requirements:

  1. All manuscripts must be formatted using the journal's docx/odt or latex templates.
  2. All files must be submitted as PDFs during the peer review process.
  3. Submissions may contain at most two PDF files, one for the manuscript and another for the supplementary materials. If possible, the two files should be merged into a single PDF.
  4. Manuscripts must contain an article summary, abstract, author contributions statement, data and code availability statement, and a competing interests statement.
  5. All authors must have an ORCID iD.
  6. Figures must respect the journal's resolution requirements (see below).
  7. References must be formatted using the style of the American Psychological Association (APA) 7th edition.
  8. All references must contain a digital object identifier (or another persistent identifier) when one is available.
  9. All code and datasets must be made available to the reviewers as described in the journal's Open Science policies.

In addition to the above guidelines, authors should be familiar with the following journal policies: Authorship, Code of conduct, Plagiarism, Prior publication and self archiving, and Use of artificial intelligence.

The above requirements must be satisfied at the time of submission, without exception. Additional details are provided in the sections below.

Templates

The journal provides Latex and docx/odt templates that can be downloaded using the following links:

These templates are designed to be used with our automated production tools, and authors should not modify any of the formatting within these files (such as numbering, font size and weight, line spacing, margins, reference style, table formatting, and the order of the article components). If authors would like to suggest changes on how to improve these templates, we ask that they open an issue on our Codeberg repository.

Though we are happy to accept submissions in either docx or Latex formats, we note that our production pipeline will convert all accepted docx manuscripts to Latex. This requires extra time on our part, incurs additional cost, and is more prone to introducing errors, especially with equations. Unlike Latex submissions, we note that we are unable to hyperlink citations in the text to bibliography entries for docx submissions. When it is possible and convenient, we encourage authors to use our Latex template.

Article components

Summary

All submissions must contain an article summary that is 350 or fewer characters in length. This short summary will appear before the manuscript abstract and will also appear in the issue's table of contents. Summaries should in general be written in full sentences, though other formats may be considered when they respect the character limit.

Abstract

Abstracts must be a single paragraph and contain 250 or fewer words. All acronyms used in the abstract must be defined at the time they are first used. Abstracts should avoid citing other work whenever possible.

Figures

Following the acceptance of an article, the journal will ask for original versions of each figure. The journal accepts the following file formats: jpg, png, tiff, pdf, and svg. Each figure should consist of a single file, and if the figure is composed of several components, it is the author's responsibility to combine these into a single file.

Figures must be sized to fit in the PDF version of the manuscript. Images will appear with widths between 10 and 15 cm, and have a maximum permissible height of 22 cm. The minimum permissible dpi (dots per inch) is 150. In terms of pixels, these dimensions correspond to 590-890 × 1300.

Each figure must contain a caption. If the figure was published previously, the original source must be acknowledged. Furthermore, written permission to reuse the figure must be provided to the journal from the copyright holder if the figure is not distributed under a license permitting reuse.

Tables

Each table must contain a caption. The maximum width of a table can not exceed the width of the PDF page: The journal does not support landscape mode for large tables, and the font size used for tables in the manuscript can not be modified.

Author contributions

Each manuscript must contain an Author contributions statement that describes the role of each author in the study. Author roles use the Contributor Role Taxonomy (CRediT) as described in the journal's Authorship policies. The manuscript templates list each possible role, and those roles that are not applicable to the study should be removed.

Data and code availability

Each manuscript must contain a Data and code availability statement. This statement should mention all datasets and numerical codes that were used or generated by the study and how they can be accessed (see the journal's Open Science policies). When possible, datasets should be cited and listed in the References section.

Funding

All sources of funding for the work must be disclosed. For work funded by a research agency, the following information should be provided: The name of the funding agency, the name of the funding program, the title of the funded project, and the grant number or funding reference.

Competing Interests

All manuscripts must contain a Competing interests declaration that describes any real or perceived conflicts of interest.

References

References and in-text citations must follow the formatting guidelines of the 7th edition of the American Psychological Association (APA) style guide.

Appendix

Appendices are optional sections that follow the open science statements. All figures and tables in the appendix must be referenced in the text of the appendix, and figure, table, and equation numbers should be prefixed by the appendix letter (such as Figure A1).

Supplemental materials

Each manuscript may contain at most a single PDF of supplemental materials. This file must be formatted using the journal's template and will not be reformatted by the journal. Supplemental materials may include text, figures, tables, and references. Supplemental figures and tables should be labeled using the prefix S, such as Figure S1. Supplemental references should include only those works that are cited within the supplemental materials. Supplemental references are unlikely to be indexed by citation databases.

If the manuscript has additional supplementary materials, such as movies, spreadsheets, or datasets, these will eventually need to be uploaded to a data repository and cited in the manuscript in accordance with the journal's open science policies. During the review process, however, these files can be shared with the reviewers using a simple file sharing download link.

Letters

Letters are manuscripts that are formatted in a similar manner to articles, but that have strict restrictions on their length. Letters must contain fewer than 4500 words in the combined abstract, main text, and captions (which excludes the title, authors, author affiliations, acknowledgements, references, and other declarations). Letters may contain a maximum of three figures or tables. In contrast to articles, letters do not contain appendices, but instead include a methods section that follows the main text and that is no more than 3000 words in length (excluding references). Letters may contain a single PDF of supplemental figures, tables and references, but not supplemental text.

Funding sources

Sources of financial support, if any, must be clearly disclosed in the Acknowledgements section.

Measurement units and numerical values

Measurements and numerical values should be reported using the International System (SI) of Units.

Color maps

Figures that use color must use a perceptually uniform color map that can be interpreted by those with common forms of human color-vision deficiency. "Rainbow" and "jet"-like color scales should be used only when the purpose is to demonstrate how these color maps distort scientific data (see Crameri et al., 2020).

Acronyms

Acronyms should be employed in the text only when their use improves the readability of the text. All acronyms must be defined when they are first used. If an acronym appears in the abstract, it must be defined both in the abstract and in the subsequent article text.
