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. Min, C.P. Dullemond, M. Kama, C. Dominik • On the Snow Line in Dusty Protoplanetary Disks by D. D. Sasselov and M. Lecar See more Different volatile compounds have different condensation temperatures at different partial pressures (thus different densities) in the protostar nebula, so their respective frost … See more The lower temperature in the nebula beyond the frost line makes many more solid grains available for accretion into planetesimals and eventually planets. The frost line therefore separates terrestrial planets from giant planets in the Solar System. However, … See more WebFollow-up observations of an amateur-discovered system show that the planet orbits its star at the snow line, where ice giants may form.

The radii of snow lines are about a few astronomical units (au)... WebMay 8, 2024 · At larger orbital radii, beyond the snow line, the temperature is low enough that ices as well as rocky materials can condense. This extra solid material, together with the reduced gravity of the central star, allows large solid cores to form in the outer regions of a disk. ...
