Optical CCD images and polarimetry as well as near-IR observations of
the molecular core S 140N are presented. The images reveal a reflectio
n nebulosity associated with the young IRAS source 22178+6317. Two poi
ntlike sources are embedded in the reflection nebulosity. The near-IR
colors indicate an IR excess characteristic of PMS objects. The CO out
flow detected in the region is likely to be driven by these young obje
cts. Four Herbig-Haro objects are detected in our images. This is the
first detection of these kinds of objects in the S 140 molecular cloud
. The HH objects are aligned in a scale of almost-equal-to 2.5' (almos
t-equal-to 0.7 pc) and point to a faint star, located at the northern
end of the brighter HH object This star is therefore a suitable candid
ate to excite the HH objects and is likely to be a T Tauri-like star.
In addition, the star is centered on a previously detected ammonia cor
e and likely heats the high density gas. Finally, these data show that
not only high-mass stars, but also low-mass stars have recently forme
d in the S 140 molecular cloud.
