| PRV 1 |
GJ 164. Discovered by Palomar 5m/STEPS astrometry and confirmed |
|
|
using HST/NICMOS, the combined solution by Pravdo et al. (2004) |
|
|
yielded an absolute parallax of 0".0820 +/- 0".008, spectral types of |
|
|
M4.5V and M6-8V and masses 0.170 +/- 0.015 and 0.095 +/- 0.015 Msun. |
|
|
Inclination = 57 +13/-17, omega = 133 +45/-20 deg. |
Prv2004 |
|
Combined AO+STEPS analysis of this M dwarf binary yields a total mass |
|
|
0.343 +/- 0.026 Msun, individual masses 0.257 +/- 0.020 and 0.086 +/- |
|
|
0.007 Msun. Metallicity is at least solar. |
Mtc2008 |
|
Inclination = 57 +13/-17, omega = 133 +45/-20 deg. |
|
|
GJ 164 = LHS 1642. A known close binary system with a well-determined |
|
|
orbit (Pravdo et al. 2004; Martinache et al. 2009). Its separation is |
Prv2004 |
|
smaller than 100 mas at all times, and it therefore remains unresolved |
Mtc2009 |
|
by AstraLux. We do detect one other point source in the field of view, |
|
|
but it is a suspected background contaminant based on its blue color, |
|
|
with dz'= 5.8 +/- 0.1 mag and di' = 5.3 +/- 0.1 mag. |
