WDS 08503+1057 FAH 1 AB : NOTES
 
 
discov_num notes refcode
SKF 363 Aa,Ab: NLTT 20346. Faherty et al. (2011) derive distance estimates for Fah2011
Aa and Ab of 28 +/- 5 and 33 +/- 5 pc, respectively, and estimate
spectral types at M5 +/- 0.5 and M6 +/- 0.5.
FAH 1 AB: Faherty et al. (2011) also determine a distance for RED 10 of 29 Fah2011
+/- 7 pc; similar distance and proper motions indicate SKF 363 and
RED 10 form a likely CPM pair at a distance of 248".
RED 10 Ba,Bb: 2MASSs J0850359+105716
Ba component is an L6V brown dwarf; LRIS spectrum shows that other
component is a background M star. Kir1999
Reid et al (2002) observations from HST and WFPC2. Paper includes mass Red2001
and age estimates, as well as discussion of L dwarf binary frequency
and semimajor axis distribution.
Burgasser et al. (2011) derive spectral types of L7 and L6, masses Bug2011
0.06 +/- 0.02 and 0.05 +/- 0.02 Msun, effective temperatures
1770 +/- 200 and 1400 +/- 170K.
Ba,Bb: Assuming a parallactic distance of 38.1 +/- 7.3 pc
(Vrba et al. 2004), Konopacky et al. (2010) derive a system mass of Vrb2004
0.2 +/- 0.2 Msun. Kon2010
