MEL 9 | GJ 900 | |
Malogolovets et al. (2007) combine all data to derive I-, K-, and | Mlg2007b | |
H-band absolute magnitudes for all three components, as well as | ||
spectral types and masses: | ||
I +/- K +/- H +/- spec mass (Msun) | ||
A: 6.66 0.08 4.84 0.08 5.11 0.08 K5-K7 0.64 - 0.67 | ||
B: 9.15 0.11 6.76 0.20 6.85 0.09 M3-M4 0.28 - 0.34 | ||
C: 10.08 0.26 7.39 0.31 7.54 0.15 M5-M6 0.16 - 0.24 | ||
BC probably form inner short-period (~20y) pair moving with A around | ||
mass center; A,BC period ~80y. Observed configuration may be due to | ||
relative tilts of orbital planes. 2MASS images show faint objects ~12" | ||
northeast and 15" south of primary; stars are probably late M dwarfs | ||
and possibly members of the GJ 900 system. |
