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 |
