LEI 3 Aa,Ab: GG Tau.
Tamazian (2002) solution includes mass determination based on an Tam2002
estimated distance.
Aa,Ab: Kohler (2011) derives orbits both coplanar and not coplanar
with the disk; only his "most plausible" orbit is tabulated in the
orbit catalog. Elements are as follows: P = 403 +67/-32 y, a = 0".429,
i = 132.5 +1.0/-2.5 deg, Omega = 131 +13/-8 deg, e = 0.44 +0.02/-0.03,
T = 2463400 +1470/-5420, omega = 19 +9/-10. Koh2011
CHN 5 AB: formerly known as LEI 3.
DIF 1 Ab1,Ab2: Di Folco et al. estimate spectral types for Ab1 and Ab2 of M2V
and M3.5V, respectively. Assuming the close pair is coplanar with the
outer diskof the system, the stars were separated by 5.1au in Dec 2012. DiF2014
