Variable Stars

Coordinator: Grigoris Maravelias

The Working Group deals with observations of variable stars, i.e. those stars that show variability in their luminosity either due to intrinsic or extrinsic factors.

Activities of the WG include: obtaining observations through visual photometry and optical imaging, organizing observing campaigns, participating in professional-amateur projects, performing data analysis, writing reports, publishing works in national and international conferences and scientific journals.
