Revisiting the Helium and Hydrogen Accretion Indicators at TWA 27B: Weak Mass Flow at Near-freefall Velocity
TWA 27B (2M1207b) is the first directly imaged planetary-mass ( M _p ≈ 5 M _J ) companion and was observed at 0.9–5.3 μ m with JWST/NIRSpec. To understand the accretion properties of TWA 27B, we search for continuum-subtracted near-infrared helium and hydrogen emission lines and measure their wid...
