ホット・ジュピター
In 2003, S. Udry and colleagues reported the discovery of a planet in orbit around HD 73256 using data from the CORALIE spectrograph. This object is a Hot Jupiter with at least 1.87 times the mass of Jupiter in an orbit with a period of 2.55 days. In 2018, K. Ment and colleagues reported an attempt to confirm the existence of this planet using Keck/HIRES data, but were unable to do so. Thus the existence of this object is disputed.
