This giant HII region, which I call the Dragon nebula
, is ionised by two WR stars (WR 152
and WR 153
) and OB stars in several embedded clusters. WR 153 and an O 8.5 star lie near the middle of the radio shell associated with this nebula.
Available distance estimates locate Sh 2-132 in the Cep OB1
association within the Perseus arm.
This nebula is also prominent in radio
In the huge Cep OB1 association (which may not be a single association). [1
This giant HII region is located at a distance of 3.18 kpc and is ionised by two WR stars and several OB stars. HD 211853 (WR 153) and an O 8.5 star lie near the middle of the radio shell associated with this HII region. [2
In 2010 the Monthly Notices of the Royal Astronomical Society published an issue with several papers on Sh 2-132, making this an unusually well studied HII region.
