Jackie BRC 38

Location of BRC 38

Information about BRC 38

Bright Rimmed Cloud 38 in IC 1396. Since it is located in the north part of IC 1396 is it often referred to as IC 1396N.
It has a C shape with the southern edge as the brightest part (Pottasch et al. 1956).
Location with intermediate mass protostars, though some (Ogura & Sugitani 1999) suggest there is probably a lot of low mass formation going on too. Wang et al. 2009 believes potential for high mass stars forming here also.
H2 jets found (Saraceno et al. 1996; Nisini et al. 2001)
Herbig-Haro objects found (Repurth et al. 2003
Observed in many wavelengths

optical (IPHAS, several optical - including Yerkes in the 1950s - coming from Chicago I have to cheer!!),

infrared (2MASS,

radio (IRAM & BIMA)

x-ray

Questions

I am sure there are a lot more!! After fooling around with wiki editing, this is all that is left in my head.

One IRAS (Infrared Astronomical Satellite) location (IRAS 21391+5802) seems to be the central point or at least this location that keeps coming up. What is this? LWS spectrum - is this as simple as long wavelength? Still unclear on what exactly the following are. I have looked them up but they are not clear in my head - maser, Herbig-Haro objects, FIR colors, MIP colors When we talk about BRC 38, are we talking about the whole C rim and globular area it half encircles? Where does the IRAS source 21391+5802 fit in our picture? Is submillimeter wavelengths (SUBA) infrared or microwave?
