HD 11506 is a main sequence star of the spectral class G0, which is orbited by the two potential exoplanets HD 11506 b and HD 11506 c . The star lies in the constellation whale and has a mass of about 1.2 solar masses .
Exoplanet candidates
HD 11506 b orbits the central star with an orbital period of 1270 days at a distance of approx. 2.43 astronomical units and has a minimum mass of approx. 3.44 Jupiter masses. The property was built in 2007 by Debra Fischer et al. discovered using the radial velocity method. HD 11506 c orbits the central star with an orbital period of 170 days at a distance of approx. 0.64 AU with a minimum mass of approx. 0.82 Jupiter masses. The object was discovered by Mikko Tuomi and Samuli Kotiranta after they were able to examine Debra Fischer's data more closely using newer computer models.
