The Journal of the American Association of Variable Star Observers is a refereed scientific journal
published by the American Association of Variable Star Observers, 49 Bay State Road, Cambridge, Massachusetts
02138, USA. The Journal is made available to all AAVSO members and subscribers.
In order to speed the dissemination of scientific results, selected papers that have been refereed and accepted
for publication in the Journal will be posted on the internet at the eJAAVSO website as soon as they have
been typeset and edited. These electronic representations of the JAAVSO articles are automatically indexed
and included in the NASA Astrophysics Data System (ADS). eJAAVSO papers may be referenced as J. Amer.
Assoc. Var. Star Obs., in press, until they appear in the concatonated electronic issue of JAAVSO. The
Journal cannot supply reprints of papers.
Page Charges
Unsolicited papers by non-Members will be assessed a charge of $15 per published page.
Instructions for Submissions
The Journal welcomes papers from all persons concerned with the study of variable stars and topics specifically
related to variability. All manuscripts should be written in a style designed to provide clear expositions of
the topic. Contributors are strongly encouraged to submit digitized text in ms word, latex+postscript, or plain-
text format. Manuscripts may be mailed electronically to [email protected] or submitted by postal mail to
JAAVSO, 49 Bay State Road, Cambridge, MA 02138, USA.
Manuscripts must be submitted according to the following guidelines, or they will be returned to the author
for correction:
Manuscripts must be:
1) original, unpublished material;
2) written in English;
3) accompanied by an abstract of no more than 100 words;
4) not more than 2,500–3,000 words in length (10–12 pages double-spaced).
Figures for publication must:
1) be camera-ready or in a high-contrast, high-resolution, standard digitized image format;
2) have all coordinates labeled with division marks on all four sides;
3) be accompanied by a caption that clearly explains all symbols and significance, so that the reader can
understand the figure without reference to the text.
Maximum published figure space is 4.5” by 7”. When submitting original figures, be sure to allow for reduction
in size by making all symbols and letters sufficiently large.
Photographs and halftone images will be considered for publication if they directly illustrate the text.
Tables should be:
1) provided separate from the main body of the text;
2) numbered sequentially and referred to by Arabic number in the text, e.g., Table 1.
References:
1) References should relate directly to the text.
2) References should be keyed into the text with the author’s last name and the year of publication, e.g.,
(Smith 1974; Jones 1974) or Smith (1974) and Jones (1974).
3) In the case of three or more joint authors, the text reference should be written as follows: (Smith et
al. 1976).
4) All references must be listed at the end of the text in alphabetical order by the author’s last name and
the year of publication, according to the following format:
Brown, J., and Green, E. B. 1974, Astrophys. J., 200, 765.
Thomas, K. 1982, Phys. Report, 33, 96.
5) Abbreviations used in references should be based on recent issues of the Journal or the listing provided
at the beginning of Astronomy and Astrophysics Abstracts (Springer-Verlag).
Miscellaneous:
1) Equations should be written on a separate line and given a sequential Arabic number in parentheses
near the right-hand margin. Equations should be referred to in the text as, e.g., equation (1).
2) Magnitude will be assumed to be visual unless otherwise specified.
3) Manuscripts may be submitted to referees for review without obligation of publication.
