HD 86226 b is a
gas giant
exoplanet discovered by the
Magellan Planet Search Program in 2010.
[1] It was confirmed in data collected by the CORALIE
spectrograph on the
Swiss 1.2-metre Leonhard Euler Telescope in 2012.
[2] It takes about 4.6 years to orbit its
G-type star and was initially believed to have a minimal mass of 0.92
Jupiters.
[3] Discovery of the second planet in the system has led to the revised mass of HD 86226 b in 2020, now estimated to be 0.45+0.04
−0.05MJ.
