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: |
