... 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....

In this case, all the files would be in the <Installation Data Directory>/stars/default directory. ...

Abstract -- Calculations are performed for the linear polarization of starlight due to extinction by aligned dust grains when the starlight traverses a medium with irregular magnetic fields. This medium is intended to represent the optically thick components of interstellar clouds which are observed to make little, if any, contribution to the polarization of starlight. ...

... We present the results of an ongoing survey of cool, late­type supergiants -- the descendants of massive O and B­type stars -- that has systematically detected magnetic fields in these stars using spectropolarimetric observations obtained with the ESPaDOnS at the Canada­France­Hawaii Telescope. Our observations reveal detectable, often complex Stokes V Zeeman signatures in the Least­Squares Deconvolution mean line profiles in a significant fraction of the observed sample of 30 stars. ...

... The NICMOS Parallel Program . Analysis . ... NICMOS observations made in parallel with the other HST instruments have produced an archive of over 2,000 images, covering a wide range of Galactic latitudes. ...
