These structured features are well explained by a combination of crystalline forsterite, crystalline enstatite, silica and glassy olivine grains.\n Among intermediate-mass young stellar objects (YSOs), crystalline silicates have already been detected, but no firm detection has been reported so far for low-mass YSOs such as T Tauri stars.
