When viewed in optical starlight scattered by dust, the nearly edge-on debris disk surrounding the A5V star b Pictoris (distance 19.3 pc; ref. 1) extends farther than 1,450 AU from the star 2. Its large-scale complexity has been well characterized, but the detailed structure of the disk's central ,200-AU region has remained elusive. This region is of(More)

Its large-scale complexity has been well characterized, but the detailed structure of the disk's central approximately 200-au region has remained elusive. This(More)
We present arcsecond-scale mid-ir photometry (in the 10.5 µm N band and at 24.8 µm), and low resolution spectra in the N band (R ≃ 100) of a candidate high mass protostellar object (HMPO) in IRAS 18151-1208 and of two HMPO candidates in IRAS 20343+4129, IRS 1 and IRS 3. In addition we present high – 2 – resolution mid-ir spectra (R ≃ 80000) of the two HMPO(More)
