Emission-Line Diagnostics of T Tauri Magnetospheric Accretion. I. Line Profile Observations

We present high-resolution spectra of classical T Tauri stars in Taurus in the range 5800–9000 Å to critically examine the current theories of magnetospheric accretion. In this paper, we focus on the emission lines of hydrogen (the higher Paschen series and Hα), He I λ5876, O I λ7773 and λ8446, the ... View More
