Extinction of Taurus, Orion, Perseus and California Molecular Clouds Based on the LAMOST, 2MASS, and Gaia Surveys II: The Extinction Law
Zhetai Cao, Biwei Jiang, Shu Wang +1
The extinction law from ultraviolet (UV) to infrared (IR) (0.2-24 m) is determined by relying on the blue-edge method and color excess ratios for some nearby molecular clouds, f…
