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 | |
