López Hermoso, RosarioAcosta-Pulido José A.Estalella, RobertGómez, G.García-Lorenzo, B.2015-02-202015-02-2020150035-8711https://hdl.handle.net/2445/63188In this work, we derive the full 3D kinematics of the near-infrared outflow HH 223, located in the dark cloud Lynds 723 (L723), where a well-defined quadrupolar CO outflow is found. HH 223 appears projected on to the two lobes of the east<br>west CO outflow. The radio continuum source VLA 2, towards the centre of the CO outflow, harbours a multiple system of low-mass young stellar objects. One of the components has been proposed to be the exciting source of the east<br>west CO outflow. From the analysis of the kinematics, we get further evidence on the relationship between the near-infrared and CO outflows and on the location of their exciting source. The proper motions were derived using multi-epoch, narrow-band H2 (2.122 μm line) images. Radial velocities were derived from the 2.122 μm line of the spectra. Because of the extended (∼5 arcmin), S-shaped morphology of the target, the spectra were obtained with the multi-object-spectroscopy (MOS) observing mode using the instrument Long-Slit Intermediate Resolution Infrared Spectrograph (LIRIS) at the 4.2 m William Herschel Telescope. To our knowledge, this work is the first time that MOS observing mode has been successfully used in the near-infrared range for an extended target.15 p.application/pdfeng(c) López Hermoso, María Rosario et al., 2015RadioastronomiaJets (Astrofísica)EstelsRadio astronomyAstrophysical jetsStarsinfo:eu-repo/semantics/article6469282015-02-20info:eu-repo/semantics/openAccess
