Scope The Astronomical Journal (AJ) was founded in 1849 by Benjamin A. Gould and was acquired by the AAS in 1941. The AJ publishes original astronomical research, with an emphasis on significant scientific results derived from observations, including descriptions of data capture, surveys, analysis techniques, and astrophysical interpretation. It takes a broad view of astronomy, extending from the solar system to observational cosmology with a tradition of papers discussing dynamical processes. The AJ serves an international community that includes authors, scientists and students through efficient and accessible communication of the science and associated techniques.

The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.

Cites per Doc

Evolution of the number of total citation per document and external citation per document (i.e. journal self-citations removed) received by a journal's published documents during the three previous years. External citations are calculated by subtracting the number of self-citations from the total number of citations received by the journal’s documents.
