SCE 1 GJ 660.1 = GJ 9588. Schneider et al. (2011) estimate spectral type of
the secondary as M9 +/- 2. Projected separation is 120 +/- 9 au. Sce2011
Aganze et al (2016) derive spectral types M1 and d/sdM7 and effective
temperatures 3800 and 2550 +80/-90 K. Masses are 0.57 +/- 0.07 and
0.084-0.091 Msun, radii 0.53 +/- 0.04 and 0.085 +/- 0.014 Rsun. The
authors suggest the possibility that unusual spectral features of the
B component may arise from contamination due to an additional
unresolved companion. Bug2016
