Athena++ radiation GRMHD code and adaptive mesh refinement (AMR) framework

Please read our contributing guidelines for details on how to participate.


To cite Athena++ in your publication, please use the following BibTeX to refer to the code's method paper:

	doi = {10.3847/1538-4365/ab929b},
	url = {},
	year = 2020,
	month = jun,
	publisher = {American Astronomical Society},
	volume = {249},
	number = {1},
	pages = {4},
	author = {James M. Stone and Kengo Tomida and Christopher J. White and Kyle G. Felker},
	title = {The Athena$\mathplus$$\mathplus$ Adaptive Mesh Refinement Framework: Design and Magnetohydrodynamic Solvers},
	journal = {The Astrophysical Journal Supplement Series},

Additionally, you can add a reference to in a footnote.

Finally, we have minted DOIs for each released version of Athena++ on Zenodo. This practice encourages computational reproducibility, since you can specify exactly which version of the code was used to produce the results in your publication. 10.5281/zenodo.4455879 is the DOI which cites all versions of the code; it will always resolve to the latest release. Click on the Zenodo badge above to get access to BibTeX, etc. info related to these DOIs, e.g.:

  author       = {Athena++ development team},
  title        = {PrincetonUniversity/athena: Athena++ v24.0},
  month        = jun,
  year         = 2024,
  publisher    = {Zenodo},
  version      = {24.0},
  doi          = {10.5281/zenodo.11660592},
  url          = {}
