I 1026 AB + TOK 422Aa,Ab: HIP 91075 was noted as a double-lined binary by
the GCS (one observation only). The separation of 86mas implies a
period of ~10yr, while the double-lined observation matches the
moderate magnitude difference (estimated masses 1.04 and 0.77 Msun.
The star is an X-ray source, so a future combined orbit could
determine masses for testing evolutionary models of young stars. The
sky around the object is quite crowded; the 9" companion I 1026 is
optical (it moves too fast). Tok2015c
I 1027 CD: CPD-27@6461.
