Comparison of the emission line profiles. Top panel: He II (blue) and N III 4100 Å lines from the X-shooter spectrum at +10 days. Bottom panel: subtracted spectrum (He II – N III, blue) and Hα for comparison (in black). The line profiles are nearly identical, suggesting the presence of double-peaked Bowen N III lines, the first such line profiles seen in a TDE to date. The discrepancy in the red wing (compared to Hα) is likely related to the imperfect normalisation and subtraction of the N III profile.
