Re: Re: How do they confirm the planet?
They could do that if they had sufficient warning of the event to train a lot of instruments on it. But since it's effectively random there's no way to predict it. You have to know that the planet is there before you can look for the planet!
Also these events are often a *long* way away - it works much further than the other planet-finding methods. So there would be very little difference between different observations.
