Open Cluster Binary Explorer
Access photometric binary-star data in a collection of open clusters
An NSF-funded research project from PI Aaron M. Geller.
This website provides public access to data products and visualization tools to explore results from our open cluster photometric binary research. Click the button below to enter the data explorer.
In short, the project uses the Bayesian Analysis of Stellar Evolution with Nine Parameters (BASE-9) software suite along with Gaia kinematics and distances and photometry from Gaia, Pan-STARRS and 2MASS to characterise the binary-star populations in a collection of open clusters. For information about our methods and results, please see the Papers section at the bottom of this page. You can access these data by clicking on the button below.
The interactive visualization above shows the open cluster population as seen from Earth, with the clusters in this study highlighted in pink.
