Scientific paper
We present a multiwavelength study of the interstellar medium around the HII region Sh2-54. The millimetric and infrared data allow us to analyze and characterize the molecular gas and dust components, respectively. The emision at 8.0μm of Spitzer-IRAC shows a complex filamentary structure of photodissociated gas, revealing the interaction between the HII region and the molecular material. Several young stellar object (YSO) candidates have been detected projected towards Sh2-54 and its surroundings. We analyze if the presence of these YSO candidates can be explained by a triggered star formation scenario.
