The infrared spectral features of circumstellar envelope of evolved low- and intermediate-mass stars

Zhang, Ke; Jiang, Biwei

The circumstellar envelope of evolved stars of low- and intermediate-mass is an important site for dust formation. In comparison with the interstellar medium, they have more types of organics and different types of inorganics. Various infrared features in the circumstellar envelope can reveal the composition and abundance of dust, as well as the c…
