I 226 | Wagner et al. (2016) imaged a Jovian exoplanet orbiting the primary at | |
a distance of ~80au. They also resolved the Innes B component into a | ||
70mas pair, which they designate as B and C. However, the C component | ||
designation is already in use for Innes' 30" companion. Also, their B | ||
designation redefines B from the photocenter of the previously | ||
unresolved close stellar pair to one component of that pair. We have | ||
therefore designated the two stars as Ba and Bb, in keeping with our | ||
usual hierarchical designation scheme. | ||
Wagner et al. derive the following parameters for system components: | ||
Aa Ab Ba Bb | ||
