I’m not sure what you mean there.

What they’ve done is noted variations in transit times that might be explained by either the presence of a moon around the planet in question (the Earth’s Moon pulls our planet around, so would delay or advance Earth’s transit of the Sun, from one transit to the next, as seen from another star), or by the gravitational influence of a non-transiting planet on the orbit of the planet in question. Nothing to do with the movement of or spectral changes in the star.
