Star Formation in Molecular Cloud Cores
<=== abstract ===>
SCIENTIFIC ABSTRACT
The molecular cloud cores M17SW and Mon R2 play central roles in the
discussion of star-formation processes. In both cases previous high spatial
resolution observations show the existence of gas clumps and cool
dust condensations. Sometimes these are related to compact IR sources.
Dependent on the launch date, we propose to measure the spectral flux
distributions of deeply embedded pre-main sequence stars and presumably
protostellar condensations either in M17SW or in Mon R2. Because the energy
distributions of our targets peak at or beyond 100 microns ISO is
especially suited to supplement available submm/mm fluxes and derive
broad-band flux distributions for these examples of very early stellar
evolutionary phases.
OBSERVATION SUMMARY
M17SW: From IPAC maps and submm/mm observations by the Bonn MPIfR
Bolometer group, we selected two pre-main sequence stars and two protostellar
condensations. We propose to scan at the positions of the protostellar
condensations with PHT-C100 (filters: 60 and 100 microns) and PHT-C200
(filters: 120, 160, and 200 microns) (AOT P32: Oversampling factor = 1,
5 raster positions per scan, integration time per raster position :
13 sec (C_100) and 10 sec (C_200) ). Furthermore, the PMS objects as well
as the condensations should be observed in the single-pointing multi-
filter mode with PHT-P and filters 3.6, 4.85, 7.7, 11.5, 25, 60, and
100 microns (AOT P03).
Mon R2: We propose to scan at the position of Mon R2-IRS1 with PHT-C200 and
filters 120, 160, 180, and 200 microns (AOT P32: as above). Furthermore,
we want to get single-pointing multi-filter observations with PHT-P and
different diaphragms at wavelengths 3.6, 4.85, 7.7, 11.5, 25, 60, and
100 microns (AOT P03). In addition we will use PHT-P and AOT P03 to
observe an isolated dust clump at 25 and 60 microns.
