Alternate Definitions for Gas-to-dust ratio

Term: Gas-to-dust ratio
Definition:

The mass ratio of gas to dust. It amounts to approximately 100 in the interstellar medium, but may vary in molecular clouds and circumstellar disks due to dust grain evaporation, dust settling, condensation of gas, etc. The gas-to-dust ratio depends on the metallicity. It is larger in galaxies with lower metallicity.
