GC 22255 | Hipparcos astrometric solution adopted some elements from the orbit of | HIP1997d |
Johnson & Mayor (1986). The use of the orbital elements derived by | Jhn1986 | |
Latham et al. (1992) produces a poorer fit. | Lat1992 | |
DSG 7 | Horch et al. (2015) refer to the 280mas pair as AB; however, the B | |
component has already been assigned to the wide CPM companion of | ||
Lepine (2007). Since they refer to the 15mas as Aa,Ab the wide DSG | Lep2007 | |
pair is assigned components Aa and Ac. | ||
Aa,Ab: For the Horch et al. combined solution, spectroscopic elements | Lat2002 | |
are fixed to those of Latham et al. (2002). Assigned spectral types | ||
for Aa, Ab, and Ac are K1V, K6V, and M5V; derived masses for Aa and Ab | ||
are 0.77 and 0.64 Msun. | Hor2015 | |
Teff : A = 5252 K, B = 3400 K, C = 5500 K. | Cab2018b | |
Mass (\msun) : Aa = 0.77, Ab = 0.64, Ac = 0.15, B = 0.40, C = 0.54. |
