Astrophysics Source Code Library

Summary

Welcome to the ASCLThe Astrophysics Source Code Library (ASCL) is a free online registry and repository for source codes of interest to astronomers and astrophysicists, including solar system astronomers, and lists codes that have been used in research that has appeared in, or been submitted to, peer-reviewed publications. The ASCL is indexed by the SAO/NASA Astrophysics Data System (ADS) and Web of Science and is citable by using the unique ascl ID assigned to each code. The ascl ID can be used to link to the code entry by prefacing the number with ascl.net (i.e., ascl.net/1201.001). Most Recently Added Codes 2025 Sep 01 [submitted] adstex: Automated bibliography builder for astronomy literature adstex automatically identifies all citation keys in a TeX source file and builds the corresponding bibliography file (.bib file) by fetching the reference information from NASA's Astrophysics Data System (ADS). adstex recognizes all variants of the cite commands in TeX, and works with various styles of citation keys, including arXiv IDs, DOIs, and ADS bibcodes. When a citation key is in the format of first-author name and year, adstex will query NASA's ADS and return a list of possible reference matches for the user to select the intended one. When a reference entry has updated information on NASA's ADS, adstex can detect such changes and fetch the new information and update the user's bibliography file. adstex supports any reference entry that is available on NASA's ADS, and allows the authors to write papers without manually searching for the bibliography entries. 2025 Aug 31 [ascl:2508.022] IAR_Model: Autoregressive model to irregularly spaced data IAR_Model fits unequally spaced time series from the Irregular Autoregressive (IAR). Available as Python and R functions, IAR_Model can generate observations for each process, compute the negative of the log likelihood of these process, fit each model to irregularly sampled data, and test the significance of the estimate.
