Abstract:
Far-UV photons (FUV) strongly affect the physical and chemical state
of molecular gas in the vicinity of young massive stars.
Finding molecular tracers of the presence of FUV radiation fields in
the millimeter wavelength domain is desirable because IR diagnostics
(for instance PAHs) are not easily accessible along high extinction
line-of-sights. Furthermore, gas phase diagnostics provide information
on the velocity fields.
Description:
We have obtained maps of the HCO and H13CO+ ground state lines towards
the Horsehead edge at 5" angular resolution with a combination of
Plateau de Bure Interferometer (PdBI) and the IRAM-30m telescope
observations. These maps have been complemented with IRAM-30m
observations of several excited transitions at two different
positions.
