Time evolution of the water snowline in viscous discs

We model the evolution of the water snowline in a protoplanetary disc from its birth to death. Since the disc forms from the collapse of the molecular cloud core, the core properties influence the snowline evolution. For the case of low angular momentum of the core, the disc is gravitationally stable. There is a unique snowline in the disc. It moves outward during the core collapse and then shrink...
