Ground-based Exo-planet discoveries Options

[Guest_PhilCo126_*]

Well-known exoplanet researcher Dr Michel Mayor ( discoverer of Peg 51b with Dr Didier Queloz in 1995 ) today announced the discovery of the lightest exoplanet found so far. The planet, “e”, in the famous system Gliese 581, is only about twice the mass of our Earth. The team also refined the orbit of the planet Gliese 581 d, first discovered in 2007, placing it well within the habitable zone, where liquid water oceans could exist:

Of course it's more exciting, but only in the "All stars are actually anti-matter/matter reaction driven" sort of sense. There's no reason to support it, and there's already other ideas that better explain what is observed.

Planet hosts are lithium poor. Planets not known to have stars are lithium rich.
(anti)correlation has something to do with planets (or planet formation).

This trend only shows up for stars within +/- 100 K of Sol's effective temperature.
(anti)correlation has something to do with the structures of stars +/- 100 K of Sol's effective temperature.

Even in our solar system, the planets (or the process of their formation) were able to cause Sol to become lithium poor. There is no evidence for any of our planets having exploded in the past.

Does the idea of a exploding companions explain why only near-stellar T_eff stars display this correlation?
Does it explain why binary stars in the same temperature range do not?
Is there any evidence for planetary companions blasting their neighbors and screaming?

Consider the 16 Cygni system. Two sun-like stars: the lithium-poor star hosts a planet. The lithium-rich star hosts an M-dwarf.
