El medio interestelar en los alrededores de la region HII Sh2-183

Abstract

We present a multiwavelength study of the HII region Sh2-183, located at(,) = (123.3,+3.0) at a distance of 7.0 1.5 kpc from the Sun. Based onthe radio continuum data we estimated the amount of ionized gas, theelectronic density, and the number of ionizing photons needed to keepthe region ionized, which is important since the star/s responsible ofthe region was/were not detected yet. On the other hand, based on IRASdata we have analyzed the dust temperature and distribution. The Hi linedata allowed the detection of a shell-like structure surrounding theionized gas and the CO data revealed the presence of 6 molecular cloudsprobably related to Sh2-183, which harbor several young stellar objectcandidates.
