We study a 5' × 5' region surrounding a compact HII region IRAS 10427-6032 using multi-wavelength observations. We identified 29 Class II and 5 Class I young stellar object (YSO) candidates, most of which are oriented along the western rim of the bubble, and are spatially coincident with a cold dust clump that partially protrudes into the ionized region. The Lyman continuum luminosity of the ionized emission indicates the spectral type of the ionizing source to be earlier than B0.5-B1. The column density maps of the region, constructed using the Herschel data, show a lower density in the bubble than in the annular region. The peak values of the temperature and column density are found to be ∼21 K and 1.3 × 1022 cmr2, respectively. Stars: mid-IR bubbles, HII region.
