| 73 | So the radiation will not induce appreciable changes in the temperature. |

| 79 | I expect a swift increase in the radiative energy of the core such that, Erad >> Egas. More precisely, given the diffusion time from sink to boundary is 24 days, we can get a 'diffusion speed' and use it to calculate the time for the diffusion wave to hit any part of the core. At that point, the Erad >> Egas, and thus, we can expect significant heating of the gas (so long as the coupling time is short). |

| 81 | Consider this is the case for small pre-stellar cores, and perhaps why radiative feedback is so important. With high mass star formation it will inevitably take longer to heat the gas. |
