19 Oct 2010: Simpson et al. (2010) infer the orbital inclination 44 deg. from the parent star rotation, deriving a planet mass 1.5+2.5-0.5MJ; but the coplanarity of stellar equator with planet orbits is generally not demonstrated.
20 oct. 2002: The hypothetical planet epsilon Eridani c is suspected from the dust ring morphology (Quillen & Thorndike 2002)
2001: Marcy et al. claim that " The Doppler behavior of magnetically active stars remains poorly explored, because so few stars are as active as Epsilon Eridani. Thus, Campbell's interpretation of a planet remains controversial."
