Description

We report new mid-infrared (MIR) observations of the remarkable object IRAS 15099-5856 using the space telescopes AKARI and Spitzer, which demonstrate the presence of prominent crystalline silicate emission in this bright source. IRAS 15099-5856 has a complex morphology with a bright central compact source (IRS1) surrounded by knots, spurs, and several extended (∼4′) arc-like filaments. The source is seen only at ≥10 μm. The Spitzer mid-infrared spectrum of IRS1 shows prominent emission...[Show more]
