Abstract:
Optical and near-infrared spectroscopy of molecular hydrogen in
interstellar shocks provide a very powerful probe of the physical
conditions that prevail in interstellar shocks.
Integral-field spectroscopy of H2 in the optical wavelength region and
complementary long-slit near-infrared spectroscopy towards HH91A are
used to characterize the ro-vibrational population distribution among
H2 levels with excitation energies up to 30000cm-1.
Description:
Optical spectroscopy of HH91A was carried out during the nights of
Feb. 15 and 16, 2004, using the Potsdam Multi-Aperture
Spectrophotometer PMAS at the Calar Alto 3.5m telescope.
