Thanks.

eVLBI is the process of using high speed networks to connect radio telescopes separated by large distances (100-1000s of km) instead of the traditional method of recording onto magnetic tape and shipping the recorded data to a central correlator.

"In addition to this high spatial resolution, AMBER also provides astronomers with a spectral resolution up to 10000, corresponding to a velocity of 30 km/s."

I am curious as to what degree this improved "spectral" resolution might allow the discriminaton of planets amid the glare of home stars.

If one isolated those particular frequencies associated with atmospheric oxygen and water, adjusting for the speed of orbital motion, would it be possible to discern the reflection of some planets which might otherwise be lost in the broad spectrum of the parent star?
