Remarks

24 Sep. 2008: As Explained by Schmidt and Neuheuser (2008), "the probability for CT Cha not being bound and not orbiting each other, but being independent members of Cha I is very small, namely 4 * 10^(-3) or 0.4 %
18 Sep. 2008: Schmidt et al (2008) say that they "cannot yet exclude [parent star and companion] being independent members of Cha I, thus, not orbiting each other."
