Poster Title
SuperWASP and VeSPA: Giving results back to citizen scientists
Institution
The Open University
Abstract (short summary)
The SuperWASP Variable Stars project on the Zooniverse asks citizen science volunteers to classify light curves in order to identify candidate variable stars. Volunteers are presented with folded lightcurve plots, generated from archive data collected by the SuperWASP exoplanet search. The volunteers classify each plot by its shape, choosing one of: pulsator; EA/EB (detached eclipsing binaries); EW (contact eclipsing binaries); rotator; unknown (miscellaneous periodic shapes); or junk (no periodic shape). In its first two years, the project received 1 million volunteer classifications from 4,500 users. We are now preparing the first release of aggregated classifications from the project, containing 148,522 candidate variable stars. This will be published online via an open-access website called VeSPA: The SuperWASP Variable Star Photometry Archive. VeSPA will allow volunteers to interactively explore and download the results of the project, as well as providing a catalogue of variable star candidates for professional astronomers to use. Users will be able to look up objects by ID and perform cone searches, and filter on parameters such as variable star type, period length, and magnitude. Results will be available to download in CSV format, and raw (unfolded) photometric data will be available in FITS format.
Plain text (extended) Summary
We’re classifying variable star light curves using the Zooniverse. Results are soon to be published on superwasp.org in a way that will be accessible to citizen scientists. The first data release comprises consensus classifications of 190,063 light curves: 25,730 pulsators; 56,582 rotators; 36,382 contact eclipsing binaries; 29,882 detached eclipsing binaries; and, 41,541 unknown sources which seem to have periodic variations. The archive can be searched by coordinates or by common object name, making it easier for the public to use as well as professional astronomers. The archive currently includes results from over 1 million individual classifications from 4,500 volunteers of over 500,000 sources. This represents about a third of the total catalogue. We intend to keep the archive updated with new results and refined classifications, with results from another million classifications
coming soon after launch. To read more about our results see Thiemann+ 2021
