Abstract:
The objective of this work is to study in detail the temperatures of
dust and gas in the photon-dominated region S140, especially around
the deeply embedded infrared sources IRS1-3 and at the ionization
front. We derive the dust temperature and column density by combining
Herschel PACS continuum observations with SOFIA observations at
37um and SCUBA data at 450um. We model these observations
using simple greybody fits and the DUSTY radiative transfer code. For
the gas analysis we use RADEX to model the CO 1-0, CO 2-1, 13CO 1-0
and C18O 1-0 emission lines mapped with the IRAM-30m telescope over
a 4' field. Around IRS 1-3, we use HIFI observations of single-points
and cuts in CO 9-8, 13CO 10-9 and C18O 9-8 to constrain the amount
of warm gas
Description:
Reduced IRAM data, after applying basic routines in GILDAS (e.g.
baseline correction), converted to main beam temperatures. The
molecule-transition is indicating in the name of the file.
CO transitions as observed with HIFI and the PACS observations were
reduced using HIPE 9.1.
