MET 11 | Metchev & Hillenbrand say the F, G, H, I, J, and K components are all | Met2003 |
probably optical companions of Vega. Physicality of the Ia,Ib and | ||
Ka,Kb pairs is unknown. | ||
MBA 2 | Macintosh et al. (2003) made a K-band search for extrasolar planets in | MBA2003 |
the dust surrounding Vega, using Keck, NIRC2, and AO. The relative | ||
motions for these 7 objects between 2002 Feb and 2002 Aug were all | ||
well below expected motions for true companions, leading to the | ||
conclusion that all these faint companions are background stars. | ||
Identities of the objects discovered by Metchev et al. and Macintosh | ||
et al. are as follows: | ||
MET 11AF = Met2003 object 1 = MBA2003 object 1 | ||
MET 11AG = Met2003 object 2 = MBA2003 object 2 | ||
MET 11AH = Met2003 object 3 = MBA2003 object 3 | ||
MET 11A,Ia = Met2003 object 4 | ||
MET 11A,Ib = Met2003 object 5 | ||
MET 11AJ = Met2003 object 6 = MBA2003 object 7 | ||
MET 11A,Ka = Met2003 object 7 | ||
MET 11A,Kb = Met2003 object 8 | ||
MBA 2AL = MBA2003 object 4 | ||
MBA 2AM = MBA2003 object 5 | ||
MBA 2AN = MBA2003 object 6 | ||
