Our photometric monitoring reveals Gl649 to be a new variable star with brightness changes on both rotational and decadal timescales. However, neither of these timescales are consistent with the 600-day Doppler signal and so provide strong support for planetary reflex motion as the best interpretation of the observed radial velocity variations. Gl649b is only the seventh Doppler-detected giant ","authors_text":"Andrew W. Howard, Brendan P. Bowler, Debra A. Fischer, Geoffrey W. Marcy, Gregory W. Henry, Howard Isaacson, Jason T.
