... Bispectrum speckle interferometry and future long-baseline interferometry of the young bipolar outflow source S140 IRS1 . ... 2003SPIE.4838.1047P We present bispectrum speckle interferometric observations of the deeply embedded protostellar outflow source S140 IRS1. ... Our image shows the circumstellar environment of S140 IRS1 in unprecedented detail and suggests that the central source is marginally resolved with a FWHM diameter of approximately 20 mas (approx 20 AU). ...

... Study of Mg-Fe-silicate glasses of variable composition. ... With the new data, the astrophysical discussion started in Paper I was continued and focussed on the comparison of the olivine glass data with IRAS LRS spectra of O-rich circumstellar envelopes around Mira stars. ... The new olivine glasses point to the interesting consequence that the temperature for silicate dust grains at the inner edge of circumstellar envelopes must be considerably higher than the values often given in the literature....
