The determination of the physical conditions in molecular clouds is a keystep towards our understanding of their formation and evolution of associatedstar formation. We investigate the density, temperature, and column density ofboth dust and gas in the photodissociation regions (PDRs) located at theinterface between the atomic and cold molecular gas of the NGC 7023 reflectionnebula. We study how young stars affect the gas and dust in their environment.Our approach combining both dust and gas delivers strong constraints on thephysical conditions of the PDRs. We find dense and warm molecular gas of highcolumn density in the PDRs.
