Hipparcos Binary Catalog

Cross-matched DEBRIS A stars with the Hipparcos Double star catalog. Found 10 stars that are confirmed double stars with minimal B and V information. Next, I'm going to investigate each star without log(g) information (~30 stars) individually.

...not much data on the individual stars.

According to Moon & Dworetsky 1985, I should be able to derive Teff and log(g) data from stromgren photometry, but only 5 stars from my list HAVE stromgren photometry available.

So once I actually derive ages for the Stromgren stars and match the other A stars to their isochrones (as in Song 2001), I will only have 13 stars with no age data.
