| YSC 133 |
A first orbit for this system was reported recently in Tokovinin et |
Tok2015c |
|
al. (2015), but those authors assumed a quadrant flip of one data |
|
|
point taken by Horch et al. (2008). That was not an unreasonable |
Hor2008 |
|
assumption based on the relatively small magnitude difference, but the |
|
|
points presented here give support to an "alternate" orbit where no |
|
|
quadrant flips are needed and the period is about half of that derived |
|
|
in the earlier calculation. Given the revised Hipparcos parallax of |
|
|
13.55 +/- 0.43 mas, the new orbit gives a mass sum of 3.5 +/- 1.0Msun, |
|
|
which is somewhat high for a system of composite spectral type F7, but |
|
|
with substantial uncertainty at this stage. In contrast, the Tokovinin |
|
|
orbit gives a mass sum of about 1 Msun, which would seem to be too low |
|
|
by roughly the same amount. |
