Supergiant Binary Stars - Video from Workshop
Below is a video from the workshop about supergiant binary stars by Dr. Doug Welch. We are in the process of posting the other video online. However, we are able to post this one quickly because it is a shorter talk than most of the others so has a smaller file size. This is an entertaining talk about supergiants, why we are interested in them and how certain properties can be used to uncover deeper understanding of the star. This talk is aimed at the level of an experienced amateur astronomer, but doesn't require knowledge of advanced astrophysics. It is a good starting point for those interested in doing some analysis later on in the Citizen Sky project. More video will be posted soon.
This is a 40MB Quick Time movie so may take a while to download. A Flash version will be posted with the other video, along with the PPT slides. A two-DVD set of all the videos has been mastered and is being copied right now. The video on the DVD will be of much higher resolution and quality.
