Authors wanted!

We invite authors and amateur researchers to publish their articles in the Variable Stars Observer Bulletin. If variable stars is your passion and you have something interesting to say to the community – go ahead and contribute! No matter whether your article is a strict scientific text reporting your advanced research results or just an overview article for amateur reading – it works. Amateur astronomy has a good commitment to the science for generations, and there is always a need in a good reading for people who are just on their way to the big science. Or just want to be in the context of contemporary progress in astronomy.

Pure scientific texts often require a solid background in math and astrophysics, but what we can do is to create a simplified overview of those papers. This intention follows a very clear goal: to provide a simple join-point for amateurs to advanced scientific research, taking into account their basic experience. For those who are interested in further reading, there are always lists of recommended publications or web references to continue with.

Authors making research in the field of variable stars are welcome to publish their articles in the following issues! Should you have an article ready for sharing with the community, just contact us, so we can schedule it. So far, we have prepared several issues, so everyone can check out the overall concept behind the project. Do not hesitate to forward your questions to "vs-compas [at] belastro.net".

Clear skies!

The VS-COMPAS Project
The project was started in fall of 2011 by four amateur astronomers from Belarus. The main intention is to expand the International Variable Star Index (VSX) catalog with new variable stars, variable stars data analysis and research. Among the most significant achievements it is worth to mention more than 1200 variable stars discovered by combined efforts of seven active team members. All data about discovered stars is submitted to the VSX catalog running by the AAVSO. Another valuable goal the project has is increasing public interest to variable stars science.
