The
ionised gas distribution has been mapped using the Giant Metrewave Radio Telescope (GMRT), India
at three continuum frequencies: 1280, 610 and 325 MHz.
The energy released now heats the
gas till it becomes an
ionised plasma due to the high Temperature, the escape of this centraally generated energy to the suface of the «cloud», now a proto star will eventually stop the collapse as the outer layers also heat, and the outer plasma will become opaque to the EM radiation generted
at the million degree buring interface.
