喬治·大衛·蓋特伍德（George David Gatewood， 拉蘭德21185爭議 儘管蓋特伍德涉入了巴納德星的行星爭議，但他並沒有放棄。至今已有157篇期刊論文發表。第一篇由約翰·赫爾希發表的論文指出這是坎普的望遠鏡造成的系統誤差。 蓋特伍德因為在1996年宣稱發現地球附近的多行星系統而受到注目，並於1996年在美國天文學會的會議上和對大眾媒體宣布在該恆星旁發現多行星系統，現為匹茲堡大學和阿利根尼天文台榮譽退休教授。以下是他近年的代表性著作： 2001 “A Combined Hipparcos and MAP Study of the Proposed Planetary System of Rho Coronae Borealis”, Ap J 548, L61.
