Fragmentary structure in the L1551 molecular outflow

Parker, Nicholas D. and White, Glenn J. (1991). Fragmentary structure in the L1551 molecular outflow. In: Fragmentation of Molecular Clouds and Star Formation, 12-16 Jun 1990, Grenoble, France, p. 480.



We have obtained a high resolution map of the 12CO J=3-2 emission in the vicinity of HH102 in the L1551 molecular outflow. The data reveal the presence of several bright clumps within the thin shell of low-velocity blue-shifted outflowing gas. There is evidence for further fragmentation in the clumps, as signified by the high derived excitation temperatures and low beam-filling factors. The region of peculiarly energetic activity asociated with HH102 concides with the projected location of impact of a radio jet from IRS56 with the dense ambient gas surrounding the outflow cavity.
