Polycyclic Aromatic Hydrocarbon (PAH) Abundances In The Disk Around T Chamaeleontis (T Cha): PAH Sizes, Ionization Fraction, And Mass During JWST Observations - Astrobiology

The T Tauri star T Cha is known to have a protoplanetary disk with a dust gap separating the inner and outer disk regions. The mid-IR JWST spectrum of T Cha show multiple prominent aromatic infrared bands (AIBs) around 6.2, 8.1, and 11.3 μm. AIBs are commonly accepted as the emission stemming from PAH molecules.
