An investigation in radio and infrared wavelengths of two high-mass star forming regions toward the southern Galactic bubble S10 is presented here .
The two regions under study are associated with the broken bubble S10 and Extended Green Object , G345.99-0.02 , respectively .
Radio continuum emission mapped at 610 and 1280 MHz using the Giant Metrewave Radio Telescope , India is detected towards both the regions .
These regions are estimated to be ionized by early B to late O type stars . Spitzer GLIMPSE mid-infrared data is used to identify young stellar objects associated with these regions .
A Class I/II type source , with an estimated mass of 6.2 M _ { \odot } , lies \sim 7 \arcsec from the radio peak .
Pixel-wise , modified blackbody fits to the thermal dust emission using Herschel far-infrared data is performed to construct dust temperature and column density maps .
Eight clumps are detected in the two regions using the 250 \mu m image .
The masses and linear diameter of these range between \sim 300 - 1600 M _ { \odot } and 0.2 - 1.1 pc , respectively which qualifies them as high-mass star forming clumps .
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 , based on the radio and MIR morphology , the occurrence of a possible bow-wave towards the likely ionizing star is explored .
