High-resolution spectra of the Hα line of the Haro 5-2A and B components, obtained with the SOAR GHTS on UT 2021-11-19. Upper panel: spectrum of the M2.5 WTTS Haro 5-2A. Lower panel: spectrum of the accreting M3-type CTTS Haro 5-2B. The vertical dashed line is set at the rest wavelength for Hα (6562.8 Å). The blue horizontal dashed line indicates the full width of the Hα profile at 10% of its full height (White & Basri 2003).
