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
