Evidence of a Disk Wind Origin for Fluorescent H2 in Classical T Tauri Stars

Evidence of a Disk Wind Origin for Fluorescent H2 in Classical T Tauri Stars

We use far-ultraviolet spectra of 36 T Tauri stars, predominately from the Hubble Space Telescope (HST) ULLYSES program, to examine the kinematic properties of fluorescent H _2 emission lines for evidence of disk outflows. Leveraging improvements to the HST Cosmic Origins Spectrograph wavelength sol...
