re: Alberto? It was no joke; GQ Lupi does indeed have a planet.
"I hope to e-mail the German astronomers who recorded the image and petition them to try and record any possible Doppler-shift variations
in the gas-giant's orbital velocity caused by potential moons"
The object out at nearly 100AU is moving too slowly to have its orbital velocity detected. I think this was mentioned in one of the original articles. I also think you need a fairly bright object to get a clear enough spectrum do the doppler thingy, even with Keck class scopes.
