CST 8 | AB: IR sources in rho Oph cloud. | |
A component = V2247 Oph = SR 12 = HBC 263 = ROX 21. | ||
1986.4: 0.45 - 0.18 flux ratio in J band, 1.00 - 0.35 in H band | Smn1987 | |
ALO 7 | AC: Kuzuhara et al. (2011) confirm that the C component is a member of | Kuz2011 |
the rho Oph star-forming region and is physically associated with the | ||
AB pair. The mass of C is estimated at 14 +7/-8 Mjup. |
