Abstract

We present a multi-wavelength analysis of the southern infrared bubble S10. Radio continuum emission is detected towards the bubble at 610 and 1280 MHz, and the bubble is estimated to be powered by massive stars of spectral type B0.5 – B0. A Class I/II type source, with an estimated mass of 6.2 M_ʘ, lies ~ 7” from the radio peak. Six massive clumps capable of forming massive stars are detected from the Herschel 250 µm image. Modelling of the spectral energy distribution of these clumps indicates the presence of high luminosity, high accretion rate, massive young stellar objects possibly in the accelerating accretion phase. Further, the occurrence of a possible bow-wave towards the likely ionizing star is explored.
