The units are a little unusual: log10 of opacity on the vertical axis, and log10 of temperature in millions of Kelvin on the horizontal axis. The solid line corresponds to a density closest to the Sun's photosphere. Exercise:

WebOptical depth in astrophysics refers to a specific level of transparency. Optical depth and actual depth, and respectively, can vary widely depending on the absorptivity of the astrophysical environment. Indeed, is able to show the relationship between these two quantities and can lead to a greater understanding of the structure inside a star.
