Thank you everyone for this discussion, very interesting. So the planet is most likely a hot lava like planet, ouch and a pity as it is the closest.
That is if we haven't ruled out other planets orbiting either star.
Alpha Centauri Bb is the only planet we've detected in that system so far
, because it's the easiest one to detect using our methods. As I believe I remarked above, we don't yet have the technology to detect an Earth-sized planet in the habitable zone of either star. So it's way too early to rule out other planets in the Alpha Centauri system. It'll probably take a few more years before we have the means to see what else is there.
