HIP 49546 is an astrometric binary of 1.5yr period (Goldin & Makarov |
|
|
2006) with variable RV. The period corresponds to a semi-major axis of |
Gln2006 |
|
25mas. The star is resolved here tentatively at 26mas. This resolution |
|
|
is below the diffraction limit and needs confirmation. The measured |
|
|
position angle of 346deg is close to 342deg predicted by the |
|
|
astrometric orbit. |
