Comparison of spectrum 3 of J012026 with examples of the different transient classes discussed transients: BFFs (In green, AT 2021loi; Makrygianni et al. 2023, AT 2019avd; Malyali et al. 2023a; Frederick et al. 2021, and AT 2022fpx; Koljonen et al. 2024), TDEs with Bowen features (in blue, ASASSN-14li; Holoien et al. 2016, AT 2022wtn; Onori et al. 2025, AT 2019dsg; van Velzen et al. 2021a, AT 2018dyb; Leloudas et al. 2019, and iPTF15af, Blagorodnova et al. 2019), and TDEs with coronal lines (in yellow, AT 2017gge, Onori et al. 2022, and AT 2022upj, Newsome et al. 2024). The gray-shaded areas show, respectively from left to right, the wavelength corresponding to H_δ, H_γ, N III, He III, H_β and [O III]λ5007. The presented spectra are retrieved from the transient name server or from the ESO archive.
