Abstract:
The development
of sensitive infrared arrays and efficient infrared pectrographs over
the past 10 years has made possible the study of faint nebular objects
called Herbig-Haro Objects. From optical studies, it is known that these
objects are the product of mass ejections in jets from young stars,
a process which is apparently required for a star to evolve to a main
sequence star. The supersonic
jets interact with the ambient medium, producing radiative shock waves
which are seen as the Herbig-Haro Objects. Much of the mass outflow
driven by the jets, however, is molecular in form, and to observe the
molecular components requires both radio and infrared observations.
I report on molecular hydrogen observations obtained in the near infrared
portion of the spectrum in HH 38, HH 46/47, and HH 120. The molecular
hydrogen emission lends important clues as to how the optical flow couples
to the more extensive molecular flows seen in radio observations through
emission of CO, ammonia, and other molecules.
