Fig. 4: Disk photocenter offsets for XX Tri.
From: Long-term Doppler imaging of the star XX Trianguli indicates chaotic non-periodic dynamo
a Displacement in units of projected stellar-disk radius during a single stellar rotation (for rotation #1 in the first observing season; see Supplementary Table 1). The color bar indicates the rotational phase. b Full-time series of the radial offset, \({r}_{{{{\rm{p}}}}}=\sqrt{{x}_{{{{\rm{p}}}}}^{2}+{y}_{{{{\rm{p}}}}}^{2}}\). Dots mark the reconstructions from the Doppler images, the line marks the reconstructions including the interpolated movie images. The evolution of the radial offset of the photocenter over time is also available as an mp4 movie (Supplementary Movie 6). Source data are provided as a Source Data file.
