DOI: 10.1016/j.icarus.2017.10.031
Abstract: Planetary embryos form protoplanets via mutual collisions, which can lead to the development of magma oceans. During their solidification, significant amounts of the mantles’ volatile contents may be outgassed. The resulting H2O/CO2 dominated steam atmospheres… read more here.
