There are hints in recent visual observations of a decline in brightness for epsilon Aurigae. In this walk through, learn how to read data and the light curve to make your own decision. What do you think? "Is it real, or is it Memorex?"
A new, open-source data visualization and analysis tool called VStar is now ready for download. It is the product of a Citizen Sky programming team led by David Benn - VStar Software Development Team. We are very proud of VStar and thank the team for the many, many hours of hard work that have gone into creating this tool.
Our special guest was Grant Foster, a long-time variable star data researcher and one of the best around at describing statistics to a layperson. He is recent author of the book Analyzing Light Curves: A Practical Guide. Newbies are encouraged to ask any question, don't be shy! We recommend a quick scan of our new 5-Star Analysis Tutorial before joining the chat. Advanced folk can also attend and ask more advanced questions too, but try to save them for the later half of the talk.
The deadline to apply for the 1st round of selection is midnight (Eastern) tonight Monday, June 14th!
The second Citizen Sky Workshop will be held Friday-Sunday, September 3-5, 2010 at the California Academy of Sciences in San Francisco. We will kick-off the 3-day workshop with an opening reception and tour on the evening of September 2. The focus of this workshop will be data analysis and scientific paper writing. We will have sessions updating us on the science of epsilon Aurigae, how to use VStar for basic data analysis, how to write papers for peer review, how to choose good research questions, doing literature reviews and much more. We also will have a free showing of the new Citizen Sky planetarium trailer on the California Academy of Science's brand-new planetarium dome.
Travel grants are available.
An updated version of the multi-platform, easy-to-use variable star data visualization and analysis tool, VStar, is now available! (To download the new version simply visit the VStar page and click on "Download VStar Now.")
