WDS 17341-0303 TOK 417 (HD 159307) : NOTES

discov_num	notes	refcode
TOK 417	HIP 85963 has a variable RV and is an acceleration binary. The 91mas
	separation implies an orbital period of ~10yr; the estimated masses
	are 1.37 and 0.81 Msun. Despite extensive literature (51 references in
	SIMBAD), there is no published spectroscopic orbit, while several
	high-resolution spectroscopic studies addressed the abundance.	Tok2015c
