SCIENTIFIC ABSTRACT
This proposal is to investigate an all sky sample of dense
molecular clouds and very cold IRAS sources for evidence of
protostellar objects. The prime aim is to use of the
high sensitivity of ISO to search for pure inflow sources
with no attendant outflows, and hence investigate the very first stages
of stellar evolution. We would be able to determine the low end of the
luminosity function of embedded IR sources in these clouds, and
answer whether or not the initial mass function is truncated at around
0.7Ms as suggested by some in the literature.
OBSERVATION SUMMARY
For this part of the proposal (part 2) it is intended to observe 'very cold'
IRAS sources - defined here to have a flux at 100um of more than ten times
the 60um flux. The specific purpose is to identify 'low mass' protostars,
so objects having a 100um flux of more than 100Jy (an arbitrary limit), have
also been discarded. In a final bid to reduce the target still further, only
high priority sources, and sources with just 60um and 100um, have been chosen.
In order to achieve reasonable photometry, the minimum integration time per
filter is quoted as being 32sec. This will be used in all cases.
With the C200 filter, a strip scan will be made at 200um, adding
new science, possibly never again achievable.
The calculations of the telescope times have been made using the manuals
provided.
