Deep, coronographic J-band images of the IR-excess star ɛ Eridani show no faint companions within 18" (60 AU) of the star. In particular, no companions were noted at the position of the Greaves et. al (1998) submilimeter excess located at α (J 2000) = 03 32 57.25, δ (J2000) = -09 27 36.0. Although one J = 18.3 object was detected 17" from the star, it does not share ɛ Eridani's proper motion and is almost certainly a background object. Similarly, non-coronographic images of β Pictoris showed no companions within 20" (380 AU) of the region of submilimeter excess (α (J2000) = 05 46 57, δ (J2000) = 51 03 38), previously identified by Holland et al. (1998) as being a likely location for a faint companion. This work was supported by a NASA Origins grant to UCLA.
