The Journal of the American Association of Variable Star Observers (ISSN 0271-9053) is the research publication of the AAVSO. 

Launched in 1972 and published twice a year, The Journal (or JAAVSO) contains scholarly research articles submitted by members of the AAVSO community on a wide range of topics relevant to the AAVSO and variable star astronomy.  The Journal is also the primary publication for papers and abstracts presented at AAVSO meetings.  The Journal is a refereed publication, open to any and all amateur and professional members of the variable star research and observation community, as well as related scholarly groups such as computer and information scientists, historians, and educators.

Publication in the Journal requires a page charge of US$100/page for the final printed manuscript.  Page charges are waived for Members of the AAVSO.  With the exception of abstracts of papers presented at AAVSO meetings, papers submitted to the Journal are peer reviewed by individuals knowledgable about the topic being discussed.  We cannot guarantee that all submissions to the Journal will be published, but we encourage authors of all experience levels and in all fields related to variable star astronomy and the AAVSO to submit manuscripts.  We especially encourage students and other mentees of researchers affiliated with the AAVSO to submit results of their completed research.
