RED 9 2MASSW J0746425+200032
Reid (2001) 2000.287 data from HST WFPC2 . Paper includes mass and age Red2001
estimates, as well as discussion of L dwarf binary frequency and
semimajor axis distribution.
Bouy et al (2004) derive a combined spectroscopic/astrometric solution Boy2004
for this binary L dwarf. Quoted errors are as follows:
P: +2.475/-2.100y, a: +0".030/-0".023, i: +2.5/-3.4deg,
node: +9.9/-14.2deg, T: +0.14/-0.09y, e: +0.08/-0.09,
omega: +5.2/-5.9deg. Semi-major axis given as 2.53 +0.37/-0.28 au.
Angular values in orbit catalog are based on the quoted distance of
12.21 +/- 0.05 pc. The total derived mass is 0.146 +0.016/-0.006 Msun.
HST spectra indicate spectral types L0 +/- 0.5 and L1.5 +/- 0.5; Bouy
et al. determine age range 150-500 Myr, conclude secondary is brown
dwarf with mass in range 0.060 - 0.072 Msun.
Gizis et al. (2006) believe both stars are probably older (>1 Gyr)
than thought by Bouy et al., with masses about 0.080 and 0.075 Msun. Giz2006
Assuming a parallactic distance of 12.21 +/- 0.05 pc Dah2002
(Dahn et al. 2002), Konopacky et al. (2010) derive a system mass of
0.151 +/- 0.003 Msun. Kon2010
Astrometric orbit by Harris et al. (2015) yielded the following
properties: spectral types L0+L1.5, absolute J mags 11.85+12.21,
masses 0.080 +/- 0.002 and 0.074 +/- 0.002 Msun. USN2015
