Abstract:
We present a multi-epoch infrared photometric study of the
intermediate-mass star-forming region G173.58+2.45. Photometric
observations are obtained using the near-infrared JHKL'M' filters and
narrow-band filters centred at the wavelengths of the
H2(1-0)S(1)(2.122um) and [FeII](1.644um) lines. The H2 image shows
molecular emission from shocked gas, implying the presence of multiple
star formation and associated outflow activity. We see evidence for
several collimated outflows.
Description:
Observations were acquired with the 3.8-m United Kingdom Infrared
Telescope (UKIRT), Mauna Kea, Hawaii. Photometry in the J and K bands
was obtained on 2001 December 26 using UFTI equipped with a Rockwell
1024x1024 HgCdTe array. The region was observed again using UFTI on
2002 October 22 in the H and K bands and in narrow-band filters at the
wavelengths of the H2 v=1-0S(1) line (2.1218um) and the
[FeII]a4D7/2-a4F9/2 line (1.6439um), and on 2002 November 6,
in the J band.
