| HDS1140 | AB + TOK 394AC: This is the high-PM M-dwarf LP 784-12 (HIP 39293) at | |
| 30pc. A new distant component C was found at 1".8 in addition to the | ||
| known pair HDS 1140 which closed from 0".4 in 1991.25 to 0".33 now. It | ||
| is confirmed as physical by its fixed position during one year, the | ||
| quadrant of the triple was determined in run 5. | Tok2015c |
