VStar is the AAVSO’s data visualization and and analysis software, and is extremely useful and highly respected. You will learn about VStar’s current functionality, an appreciation of the ways in which it can be extended, and how it can be used for variable star data visualization and analysis. You’ll learn how to create mean plots, phase plots, and perform simple period analysis. This is not a course on statistics but relevant statistical concepts as they apply to the use of VStar will be introduced through reading and discussion.
VStar is written in the Java programming language, requiring at least version 1.6 to run on Windows, Mac OS X, Linux, and OpenSolaris. Questions? Contact Elizabeth Waagen, eowaagen@aavso.org
