YSC 134 |
Metal-poor SB2, spectroscopic orbit published by Tokovinin (1991). |
Tok1991 |
|
An astrometric orbit was deduced from Hipparcos data by Jancart et al. |
Jnc2005 |
|
(2005). The period derived for the visual orbit matches both the |
|
|
spectroscopic and astrometric solutions within the uncertainty, and |
|
|
other orbital parametrs are in reasonable agreement with the Tokovinin |
|
|
solution. The updated Hipparcos parallax (39.98 +/- 0.73 mas), |
|
|
combined with the orbit, yields a mass sum of 2.0 +/- 0.3 Msun. The |
|
|
composite spectral type is K3V; a magnitude difference of 0.8 mags |
|
|
makes the component spectral types roughly K1V + K4V, which suggests |
|
|
a mass sum of 1.2-1.5 Msun, accounting for the lower metallicity. |
Hor2012b |
|
For the Horch et al. (2015) combined solution, spectroscopic elements |
|
|
are fixed to those of Halbwachs et al. (2012). Assigned spectral |
HJL2012 |
|
types are K2V and K4.5V; derived masses 0.74 and 0.68 Msun. |
Hor2015 |
|
Orbital parallax is 42.01 +/- 1.08 mas. Mass of the primary is |
|
|
0.695 +/- 0.066 \msun. Mass of the secondary is 0.621 +/- 0.058 \msun. |
