WDS 03272+0944 MKT 15 Aa,Ab : NOTES

discov_num	notes	refcode
HDS 433	1975.629: Marginally resolved at 450 nm?	Bla1977a
	Hierarchical quadruple, including 51y, 145d, and 7.14d pairs
	(HDS 433AB; MKT 15Aa,Ab; and MKT 15Aa1,Aa2; respectively). The 7d pair
	is eclipsing. Nemravova et al. (2016) combine spectroscopy,	Nem2016
	photometry, and interferometry to derive orbits of all three pairs,
	yielding the following component parameters:
	Parameter Aa1 Aa2 Ab
	Mass (Msun) 2.252 +- 0.027 2.125 +- 0.027 3.89 +- 0.25
	Radius (Rsun) 1.700 0.035 1.618 0.039 2.81 0.28
	Teff (K) 10700 160 10480 130 14190 150
	Mbol (mag) 0.923 0.079 1.120 0.075 -1.14 0.22
	(Note: Nemravova et al. refer to the pairs as AC; AB; and Aa,Ab.
	However, the HDS pair was assigned components A and B at discovery.)	HIP1997
