First Detection and Modeling of Spatially Resolved Ly $α$ in TW Hya

Seok-Jun Chang, Nicole Arulanantham, Max Gronke +2

Lyman- $α$ (Ly $α$ ) is the strongest emission line in the accretion-generated UV spectra from T-Tauri stars and, as such, plays a critical role in regulating chemistry within the sur…
