Abstract:
The dark cloud Lynds 723 (L723) is a low-mass star-forming region
where one of the few known cases of a quadrupolar CO outflow has been
reported. Two recent works have found that the radio continuum source
VLA 2, towards the centre of the CO outflow, is actually a multiple
system of young stellar objects (YSOs).
We imaged a field of 5'x 5' centred on HH 223, which includes the
whole region of the quadrupolar CO outflow with narrow-band filters
centred on the [FeII] 1.644mum and H2 2.122mum lines, together with
off-line Hc and Kc filters. Our aim is to study L723 in the
near-infrared and look for line-emission nebulae associated with the
optical and CO outflows.
Description:
The image mosaics obtained with the instrument LIRIS (Long-Slit
Intermediate Resolution Infrared Spectrograph) at the Williams
Herschel Telescope are in the images directory in the Flexible
Image Transport System (FITS) standard.
