27 Hya. A is a spectroscopic binary. Spectrum composite: G8III-IV+F5V. |
|
|
AB: SHY 540. Bayesian analysis by Shaya & Olling (2011) indicates very |
Shy2011 |
|
high (near 100%) probability pair is physical. |
|
|
AB: H 6 85. |

Toyota et al. (2009) monitored the RV of the A component every 1-2 |
|
|
months between 2003 Mar - 2007 Nov, using a high-dispersion echelle |
|
|
(precision ~10 m/s). The star exhibits a linear trend in RV, with a |
|
|
slope -30 m/s/y. Toyota et al. assert that these variations are due to |
|
|
an unseen companion. Assuming a circular orbit, period is estimated at |
|
|
3400d; if the mass of A is 2.32 Msun, the minimum mass ~10 Mjup. |
