We present new results on the nature of the Herbig–Haro-like object 73 ( HHL 73 , also known as [ G84b ] 11 ) based on narrow-band CCD H \alpha and [ S ii ] images of the HHL 73 field , and Integral Field Spectroscopy and radio continuum observations at 3.6 cm covering the emission of the HHL 73 object .
The CCD images allow us to resolve the HHL 73 comet-shaped morphology into two components and a collimated emission feature of \sim 4 -arcsec long , reminiscent of a microjet .
The IFS spectra of HHL 73 showed emission lines characteristic of the spectra of Herbig–Haro objects .
The kinematics derived for HHL 73 are complex .
The profiles of the [ S ii ] \lambda \lambda 6717 , 6731 Å lines were well fitted with a model of three Gaussian velocity components peaking at \mbox { $V _ { \mathrm { LSR } } $ } \simeq - 100 , -20 and +35 km s ^ { -1 } .
We found differences among the spatial distribution of the kinematic components that are compatible with the emission from a bipolar outflow with two blueshifted ( low- and high-velocity ) components .
Extended radio continuum emission at 3.6 cm was detected showing a distribution in close agreement with the HHL 73 redshifted gas .
From the results discussed here , we propose HHL 73 to be a true HH object . IRAS 21432+4719 , offset 30 arcsec northeast from the HHL 73 apex , is the most plausible candidate to be driving HHL 73 , although the evidence is not conclusive .
