27 Hydrae is an evolved yellow giant star in the constellation of Hydra. The star is suspected to host a low-mass companion.
Substellar companion
The Okayama Planet Search team published a paper in late 2008 reporting investigations into radial velocity variations observed for a set of evolved stars, showing hints of a substellar companion orbiting the wide binary system 27 Hydrae. The orbital period is estimated at 9.3 years, but no planet has been confirmed yet.
