The snow line astronomy

The radial position of the condensation/evaporation front varies over time, as the nebula evolves. Occasionally, the term snow line is also used to represent the present distance at which water ice can be stable (even under direct sunlight). This current snow line distance is different from the formation snow line … See more In astronomy or planetary science, the frost line, also known as the snow line or ice line, is the particular distance in the solar nebula from the central protostar where it is cold enough for volatile compounds such as See more • Circumstellar habitable zone • Nebular hypothesis • Solar nebula See more • The thermal structure and the location of the snow line in the protosolar nebula: axisymmetric models with full 3-D radiative transfer by M.
