Relation between the ratio of the 0.2–2 keV X-ray luminosity over the optical g-band luminosity and the polarisation of TDEs. The left-hand panel shows the ratio L_{X(0.2 − 2 keV)}/L_g at the times the polarisation observations of the TDEs were made. Inverted triangles denote (X-ray) upper limits, whereas pentagons mark detections. The right-hand panel shows the ratio L_{X(0.2 − 2 keV)}/L_g plotted against the V-band polarisation.
