15598 2023-09-18 16:30:28 Ryan Chornock Ryan Chornock None TDE 0.087 1 The spectra (range 3500-10600 Angs) are dominated by a starlight continuum from an older stellar population with weak nebular emission lines at redshift z=0.087, diluted by a blue continuum. In comparison with galaxy templates, a broad emission feature is present near H-alpha, consistent with previous TDE spectra. 2023TNSCR2308....1C
