Astrophysics Source Code Library

The Astrophysics Source Code Library (ASCL) is a free online registry for source codes of interest to astronomers and astrophysicists and lists codes that have been used in research that has appeared in, or been submitted to, peer-reviewed publications. We seek to increase the transparency of astrophysics research by making codes discoverable for examination.

Code entries are currently stored on Starship Asterisk, the discussion forum for APOD; a codes summary, which lists all codes on one page, is updated periodically.

The ASCL is indexed by the SAO/NASA Astrophysics Data System (ADS) and is citable by using the unique ascl number assigned to each code. The ascl number can be used to link to the code entry by prefacing the number with (i.e.,

You can follow the ASCL on our blog, our low-volume Facebook or Google+ pages, or by becoming a member of Starship Asterisk and subscribing to the forum.
