DIFFUSE INTERSTELLAR BANDS AND THE ULTRAVIOLET EXTINCTION CURVES: THE MISSING LINK REVISITED

ABSTRACT A large number of interstellar absorption features at ∼4000 -1.8 m, known as the "diffuse interstellar bands" (DIBs), remains unidentified. Most recent works relate them to large polycyclic aromatic hydrocarbon (PAH) molecules or ultrasmall carbonaceous grains which are also thoug...
