“We also go to the really big telescopes, and we get very sharp images to see if there’s anything around that star that could explain it. When we’re through with all those tests, we go to the Keck or the HET or another large telescope and we measure the spectra.
“If the spectra show that the star is wobbling, we get the mass of a planet. In particular, we can go to the Keck, get the period of the planet and get the epoch (where the planet is on its orbit). And that should exactly match what we have with Kepler. If they have the same orbital period and they occur at the same time, we can say yes, we have a confirmation and can announce it.”
THE TEXAS SCRIBBLER 
I hope they will pick up a good one soon.
The latest scifi theme has it that even when they find earthlike planets, they find no sentient life. Hope it’s not that boring.
