Caption: Figure 8.
Three spectra of T Tauri star 2M 0518−05 (dark-green, red, and blue lines), observed on 2016 August 2 and 2017 February 23, compared to an M6 dwarf template (green, red, and blue dashed lines). The T Tauri spectra with the M6 dwarf template subtracted (light-green, red, and blue lines) show excess emission similar to that expected from flares, including elevated blue continuum and emission lines. The TiO features found in both the template and 2M 0518−05 are labeled in the bottom spectrum. The Hα line profiles (shown in the inset) are wide, variable, and multipeaked, providing additional evidence that this object is showing activity primarily due to accretion rather than magnetic fields.
