B 1863 | AB + TOK 418AC: B 1863 is a known close binary which has been | |
unexpectedly found to be a triple. The new distant component C is | ||
detectable also in the y filter, but we measured only the inner binary | ||
in y. The star was observed at the Blanco telescope in 2008.5397, and | ||
the pair actually measured then was AC, at 133.8deg, 0".217, dy =3.7. | ||
The inner pair AB with a smaller dm was unresolved in 2008.5, while it | ||
is clearly resolved now. Owing to the large distance from the Sun, we | ||
expect only a slow motion, so even the inner pair observed since 1929 | ||
may not yet be ready for computing its first orbit. | Tok2015c |
