They might be too early for planets, at least rocky ones. I'm not exactly sure of the timeline for these stars, but planets require at least a generation or two of stars and novas to fuse heavy elements, and we're probably looking at some of the earliest stars formed (assuming it they are actually stars, not entirely clear yet).

Also, if they're not sure how the stars themselves can survive being so close to each other, stable planetary orbits are probably right out. :D
