HJ 5453 LDS 43. HIP 6130. See Allen et al. (2000) for information on AlC2000
metallicity, age, galactic orbital parameters, etc.
AB: NLTT 4362/4361 Chm2004
EGN 1 Aa,Ab pair bound. Colors of Ab component consistent with M2-M5 dwarf,
with mass 0.24 +/- 0.01 Msun. B component is K7 dwarf and shares
CPM with A. C component is likely a background star. Egn2007
