Temperatures of dust and gas in S 140

Context. In dense parts of interstellar clouds (≥105 cm-3), dust and gas are expected to be in thermal equilibrium, being coupled via collisions. However, previous studies have shown that in the presence of intense radiation fields, the temperatures of the dust and gas may remain decoupled even at h...
