The closest extrasolar planet: A giant planet around the M4 dwarf Gl
... The large amplitude and moderate period of the radial velocity variation argue strongly for orbital motion as its cause. An integration of the radial velocity curve implies a minimum physical motion of ∼0.5 R⊙ . This variation is about twice the radius of an M4 dwarf (Baraffe & Chabrier, 1996; Chabr ...
