WDS 16454-7150 B 2392 AB : NOTES
 
 
discov_num notes refcode
B 2392 AB + TOK 411Aa,Ab: HIP 82032 is located in a crowded field, so the
new faint Ab companion found here at 1".3 could be optical. The star
was observed because of its suspected variable RV (GCS), but the newly
found companion, even if physical, is too distant to explain this
variability. Another visual companion B at 11".5 (AB = B 2392) is
optical, as evidenced by its fast relative motion. The star is on the
HARPS exo-planet program. Tok2015c
