利用ADS、AAS和astro-ph的数据，对1999年和2002年发表在《ApJ》上的论文的发表、预印本和引文模式进行了研究。这使我们能够跟踪作者人口统计趋势，预印本发布习惯，以及ApJ论文的整体引用率，以及不同子组和类型的ApJ论文。最有趣的结果是天文学各个分支使用astro-ph服务器的频率，以及这种发布对随后ApJ论文的引用历史的影响。到2002年，72%的ApJ论文以astroph预印本的形式发表，但在研究的子领域中，这一比例从22-95%不等。这些预印本中的大部分（61%）是在论文被ApJ接受后发布的，88%是在论文被接受后发布或更新的。平均而言，发表在astro-ph上的ApJ论文被引用的次数是未发表在astro-ph上的论文的两倍多。这种差异可以解释其他一些次要引用趋势，包括期刊和不同子学科之间引用率的一些差异。预印本显然已经取代了期刊，成为最初了解论文的主要手段，至少对ApJ作者社区的很大一部分来说是这样。然而，在广泛认可的同行评审期刊上发表仍然是论文影响的主要决定因素。例如，发表在astro-ph上的会议论文被引用的频率是未发表的论文的两倍，但总体而言，这类论文的被引用频率仍比ApJ上的平均论文低20倍。这些结果提供了关于天文学研究目前是如何被作者传播和被读者吸收的见解。
We have used data from ADS, AAS, and astro-ph, to study the publishing, preprint posting, and citation patterns for papers published in the ApJ in 1999 and 2002. This allowed us to track statistical trends in author demographics, preprint posting habits, and citation rates for ApJ papers as a whole and across various subgroups and types of ApJ papers. The most interesting results are the frequencies of use of the astro-ph server across various subdisciplines of astronomy, and the impact that such posting has on the citation history of the subsequent ApJ papers. By 2002 72% of ApJ papers were posted as astro-ph preprints, but this fraction varies from 22-95% among the subfields studied. A majority of these preprints (61%) were posted after the papers were accepted at ApJ, and 88% were posted or updated after acceptance. On average, ApJ papers posted on astro-ph are cited more than twice as often as those that are not posted on astro-ph. This difference can account for a number of other, secondary citation trends, including some of the differences in citation rates between journals and different subdisciplines. Preprints clearly have supplanted the journals as the primary means for initially becoming aware of papers, at least for a large fraction of the ApJ author community. Publication in a widely-recognized peer-reviewed journal remains as the primary determinant of the impact of a paper, however. For example, conference proceedings papers posted on astro-ph are also cited twice as frequently as those that are not posted, but overall such papers are still cited 20 times less often than the average ApJ paper. These results provide insights into how astronomical research is currently disseminated by authors and ingested by readers.
