Multiwavelength Observations of the Infrared Dust Bubble N75 and its Surroundings
Infrared dust bubbles play an important role in the study of star formation and the evolution of the interstellar medium. In this work, we study the infrared dust bubble N75 and the infrared dark cloud G38.93 mainly using the tracers C 18 O, HCO + , HNC, and N 2 H + observed by the 30m IRAM telescope. We also study the targets using data from large-scale surveys: GLIMPSE, MIPSGAL, GRS, NVSS, and BGPS. We found that the C 18 O emission is morphologically similar to the Spitzer IRAC 8.0 µm emission. We also found that the YSOs are mainly located in the compressed regions between bubble N75 and G38.93, suggesting that expanding feedback could have triggered star formation. The dynamical age (∼ 5.1 × 10 5 yr) of the outflow is close to the expanding age (∼ 1.38 × 10 6 yr) of the bubble N75. It could be that they both formed in the same evolutionary period.
