Title: Comets and circumstellar dust
Authors: Waelkens, C.; Waters, L. B. F. M.; Pannekoek, Anton
2000IAUJD...4E..17W Altcode:
Since comets are pristine solar-system objects, they must abound in
the circumstellar disks which surround young stellar objects. Infrared
spectroscopy is by excellence the tool to explore the composition
of these disks, and the field has received a substantial boost from
the possibilities offered by the Infrared Space Observatory ISO. We
present ISO results for the circumstellar disks of several Herbig
Ae/Be stars, pointing out their rich mineralogy and several links
with features observed in solar-system comets and interplanetary dust
particles. Several disk spectral features are clearly linked with
those found in solar-system objects, but have no counterpart in the
interstellar medium. The study of circumstellar disks of young stars
is then not only relevant for our own solar system, but also offers
new perspectives for the study of emerging planetary systems around
other stars. A striking result is that several cometary features are
also observed in the stationary disks which surround evolved binary
systems, suggesting that the formation of bodies of substantial sizes
is a natural process in dusty environments with suitable densities
and a reasonable lifetime.

Title: The Stellar Temperature Scale
Authors: Pannekoek, A.
1936ApJ....84..481P Altcode:
The methods of determining stellar temperatures from color and energy
distribution, from ionization, and from the Boltzmann function are
discussed and are shown to depend upon complicated conditions in
the atmospheres of the stars which are not sufficiently known at the
present time to permit the derivation of reliable temperatures. Direct
methods of determining the effective temperatures of stars give 33000
for class cMo and 10,5000 for class Ao. These values are regarded
as well established, their un- certainty being estimated at no more
than 5 per cent. It is suggested that from the degree of accordance
between these temperatures and those obtained by other indirect methods
information may be obtained concerning the conditions prevailing in
the at- mosphere of the stars
