... 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....

ABSTRACT . Single electron detection is desirable in systems incorporating EBCCDs. The sources of noise in single electron counting are discussed and an expression is given for the total noise. INTRODUCTION . Electron bombarded charge coupled devices (EBCCDs) have been recognized as having performance advantages over competing technologies in terms of their high sensitivity, low noise and high spatial resolution. ...
