Probing the 9.7μm Interstellar Silicate Extinction Profile through the Spitzer/IRS Spectroscopy of OB Stars
Z. Z. Shao, B. W. Jiang, Aigen Li +3
The 9.7m interstellar spectral feature, arising from the Si--O stretch of amorphous silicate dust, is the strongest extinction feature in the infrared (IR). In principle, the sp…
