Could Alpha Centaurians detect planets around Sol?

Given Alpha Centaurian have a similar level of telescope technology that we do, could they detect any of the planets around our sun? Most of the planent detection technology I've heard about would miss our tiny inner planets since they don't exert much pull on the sun. The would also miss our outer planets as they have huge orbital periods. They might be able to detect a transit but they would never be able to confirm it without waiting 12 years (Jupiter's orbital period).
However, I'm not an astronomer and I can't keep up with all the fancy gadgets. Could any of our technology in the hands of Alpha Centaurians detect any of our planetary bodies?
