Description

Sharpless 2-88 or Sh 2-88 is a region of diffuse nebulae northwest of the nebula knots Sh 2-88A, Sh 2-88B1, and Sh 2-88B2, which are all associated with Vulpecula OB1. This nebula is a HII type diffuse nebula excited by the type O8 star BD +26°3952. Both neutral and ionized gases in Sh 2-88 are between 150 and 410 solar masses and the dust mass is about 2 to 9 solar masses. The nebula is ionized by an O8.5 to 9.5V star. The structure been interacting with a HI interstellar bubble shaped by the stellar winds of BD +26°3952 and the blue O8.5II(f) star BD +25°3866. Overall, its actual structure is located 2.4 kiloparsecs away, at 23 × 15 parsecs in radius. It has a dynamical age of 1.5 million years, and a mass of 1,300 solar masses. It has an rms electron density of 9 cm–3. All separate star forming regions are 1 arcminute in diameter.
