Interstellar Group : HII Regions & Planetary Nebulae
Harriet Dinerstein, Daniel Jaffe, John Lacy
Planetary nebulae; abundances in gaseous nebulae; infrared, optical, and ultraviolet spectroscopy of emission lines; extragalactic H II regions and star formation in disk galaxies; classical novae.
Infrared spectroscopy of protostars and star forming clouds; submillimeter observations of interstellar gas, star formation regions, and protostars; physics of the dense interstellar medium; instrumentation for infrared spectroscopy.

K band spectrum of the PN Hen 2-436 in
the Sagittarius dwarf spheroidal galaxy, measured
with the GNIRS spectrograph on Gemini South
(from Dinerstein et al. 2009). Both [Kr III] 2.199
and [Se IV] 2.287 µm were detected, and are identified
in the figure.
