| Research Abstract |
We showed that the infrared spectra of red giant and supergiant stars are hybrid of at least two components originating in photosphere and extra molecular condensation (or referred to as Molsphere).
We showed that the infrared spectra of brown dwarfs can be interpreted consistently if we regard the critical temperature, which we introduced as a parameter to represent the thickness of the dust cloud in our UCM (Unified Cloudy Model), to take various values in different objects.
