The star exhibits periodic [[視線速度]] variations that are attributed to [[Starspot|stellar spots]] on the surface of the star, based on the correlation between the radial velocity and the bisector inverse slope (a quantity that parametrises the shape of the spectral lines). The time period of the variations makes it unlikely that they are caused by [[stellar pulsations]] as these would be expected to occur on much shorter timescales (hours rather than days), and the correlation with the bisector inverse slope makes it unlikely that an orbiting companion is responsible as reflex motion would not cause the line profile variations.{{R|StempelsGahm2006}}
