| 内容記述 | Beta Pic is a nearby main-sequence star with an extended dust disk, large infrared excess, and mid-infrared emission similar to that seen in some cometary spectra. We selected a sample of stars whose infrared properties resemble Beta Pic and obtained 8 to 13 micron spectra (resolution 200). We find a variety of silicate emission features among the stars in our sample, ranging from classic interstellar dust features to spectra similar to that of comet P/Halley and the laboratory spectra of Interplanetary Dust Particles (IDP's). |
