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 |
