diffuse interstellar bands

By 2000, he was working on the origin of diffuse interstellar bands.

This week's discovery goes by the name of "diffuse interstellar bands," a phenomenon first discovered back in the 1920s.

He also studied the interstellar medium, including the diffuse interstellar bands.

The discovery that diffuse interstellar bands do not originate in circumstellar envelopes (2008)

Diffuse interstellar bands (DIBs) are absorption features seen in the spectra of astronomical objects in our galaxy.

Herbig has also made prominent contributions to the field of diffuse interstellar band (DIB) research, especially through a series of nine articles published between 1963 and 1995 entitled "The diffuse interstellar bands."

It has been suggested to be a material that diffuse interstellar bands may arise from; circular Rydberg states, where the outermost electron is found in a planar circular orbit, are the most long-lived with lifetimes of up to several hours and are the most common.
