Welcome to the AAVSO's Research Portal. From this page, you can find information about obtaining AAVSO data, requesting new observations, or learning more about the AAVSO, its data, and its services for the research community. Its purpose is to facilitate your use of the AAVSO's resources in your research efforts.
See the blue boxes on the right hand side of this page to access the AAVSO data archives or to find out how to work with the AAVSO to obtain new scientific data.
The AAVSO is a unique organization dedicated to variable stars and variable star research. We house the largest and most comprehensive digital variable star database in the world. The possibilities of future research with these data are limitless. If you are interested in working with the data directly from headquarters, or if you are interested in a possible volunteer position, we might have an opportunity available for you!
Articles containing reviews and summaries of astronomical information as well as new research (by invitation only).
Variable Star Research (up to 6,000 words)
Articles on any topic of variable star astronomy, broadly including non-stellar variables such as AGN, gamma-ray bursts, and variable nebulae. Examples include: new observations, analyses of existing data, theoretical and/or computational variable star modeling.
We are happy to announce that after a few months of testing, the AAVSO's Data Usage Reports are now available to all observers again. You may subscribe to these weekly reports by visiting this page:
