Fig. 6.
Four epochs of J053018 FEROS spectra covering Hα emission wavelengths. The dashed lines highlight the predicted positions of the Hα emission line given the measured RVs of the A (black line), B (red line) and C (blue line) components. In each epoch, prominent emission lines are visible at the predicted Hα position given the measured RVs of the BC pair, whilst no emission is visible at the predicted Hα position given the measured RV of the A component.
