We analyze the relationship between open-accessibility in data, code, and paper text in astrophysics using a sample of 53,194 peer reviewed papers published between January 2021 and April 2025, drawn from NASA's Astrophysics Data System (ADS). We measure eleven quantities: open accessibility of text, open-code status, open-data status, number of grants received, code size, programming language, data repository size, citation count, number of authors, paper length, and publication date. We break down citation advantages based on six astrophysical sub-fields: Solar System, Planet, Stellar, ISM, High Energy, and Galaxies+Cosmology, determined by keywords. This is accomplished by tuning a multivariate least-squares regression model with alongside partial correlations and non-parametric tests to isolate the contribution of each facet of openness. After controlling for the aforementioned quantities, we find significant citation advantages associated with all three forms of openness: open data (+32%, p < 10^-24), open access (+26%, p < 10^-67), and open code (+16%, p = 0.003). The open-data citation advantage is present in all six sub-fields, and especially in Galaxies+Cosmology and ISM, which have the strongest cultures of sharing simulation outputs and observational data products. Open-code and open-data sharing rates are highest in Galaxies+Cosmology and HEA (~0.9% and ~2.9%), reflecting their more developed community data infrastructure, and lowest in Solar System and ISM, where data is distributed on platforms not taken into account by this study. Our findings support the long held notion that public access comes with concrete personal incentives for authors in terms of citations.
Astrophysics Source Code Library: Here we grow again!
天体物理学源代码库（ASCL）是一个免费的在线研究代码注册表;它被ADS和Web of Science索引，拥有超过1300个代码条目。它的条目越来越多地用于引用软件;自2012年以来，引用量每年翻一番，每个主要的天文学期刊都接受对ASCL的引用。资源中的代码涵盖了天体物理学研究的各个方面，并代表了许多编程语言。在过去的一年里，ASCL为用户和管理员添加了仪表板，开始为它所拥有的软件制作数字目标标识符（DOI），并添加了用户请求的元数据字段。本报告涵盖了ASCL在过去一年中的发展，以及它作为科学研究代码的少数领域图书馆之一所提供的机会。
