WDS 21400+0911 CHR 105 AB (EE Peg) : NOTES

discov_num	notes	refcode
CHR 105	Lacy & Popper (1984) discovered a previously unknown companion to the	Ppp1984
	eclipsing binary EE Peg through its effects on radial velocity and
	times of primary eclipse. Their third component, with a period of
	1464 days and a mass ratio of roughly 5 - 12, would be expected to
	exhibit a separation from the primary of ~0".03. It thus seems likely
	that the object listed here is yet another long-period member of this
	system.
