Amenable

Saskia Bruysten,Henning Engelkeown asteroids were also observed. There is an apparent difference in the albedo distribution of the asteroids as a function of size, however, this effect is probably an artifact due to a combination of factors such as faint source flux overestimation and confusion with faint background sources.

Anne Clifford,Sarah E. A. Dixond based telescopes observations carried out by both amature and professional astronomers. In this overview we will discuss only the part of the data set that is of most interest ot infrared astromers, namely the nucleus and the dust. The molecular emission has been dealt with in another chapter.

As well as indicating that the 60 .m emission from this region comes in a large part from dust associated with the extended low density . regions, this provides a way of separating the thermal and synchrotron components of the radio emission.

We show that altough most of the emission comes from interstellar matter not associated with current star formation, about half of the heating of grains is provided by ultraviolet photons radiated by stars younger than few 10. yrs.

Taking into account the various constraints on the different dust components, in particular coming from IRAS data, we show that a bimodal rather than continuous size distribution between small and big grains is the most favorable solution.

The dominant dust heating mechanism appears to be ultraviolet radiation, either from stellar wind shooks or direct stellar radiation from hotter stars. The infrared luminosities from these extended emitting regions are often an appreciable fraction of that of the central star.
