Description

From GalaxyMap:

This HII region is associated with an expanding bubble surrounding Cep OB2. Also associated with this bubble are the HII regions IC 1396 (also called Sh 2-131), Sh 2-129, Sh 2-133, and Sh 2-140.

Avedisova concludes that the 40 solar mass O6 Iab supergiant Lam Cep (HD 210839) is the exciting star for Sh 2-134. You can read about the controversy around the origin of this great Milky Way beacon star in the Cep OB2 section of the Clamshell (110° - 100°) sector portion of the Commentary on the Galactic Plane.

Sh 2-131 and several other H II regions, such as Sh 2-129, Sh 2-133, Sh 2-134, and Sh 2-140 are apparently parts of the Cepheus bubble. [1]
