WSI 77 |
The 10.3 yr SB1 orbit by Abt & Willmarth (2006) matches the speckle |
AbH2006 |
|
pair WSI 77 and explains the large dmu. |
Tok2012a |
|
Astrometric binary. Hipparcos parallax 51.35 +/- 0.45 mas. Dynamical |
|
|
parallax 50.3 mas, masses 0.99 and 0.63 Msun. WSI 77 is a |
|
|
chromospherically active G5 dwarf within 20 pc from the Sun. According |
|
|
to Abt & Willmarth (2006), it is also a single-lined spectroscopic |
AbH2006 |
|
binary with 10.3 yr period. We used RVs from that work and the average |
|
|
RV from Nidever et al. (2002) together with four speckle points for |
Nid2002 |
|
the combined orbital solution presented. The spectroscopic elements |
|
|
are K1 = 6.06 +/- 0.25 km/s and V0 = 5.38 +/- 0.10 km/s, the rms |
|
|
residual in RV is 0.11 km/s. The node listed in Table 3 corresponds to |
|
|
the primary component, therefore Omega was chosen to describe the |
|
|
secondary’s relative motion. The pair was "caught" at close separation |
|
|
in 2012. |
