DOI: 10.1016/j.nme.2017.01.002
Abstract: Plasmas in machines with all metal plasma facing components have a lower Zeff, less radiation cooling in the scrape-off layer and divertor regions and are prone to impurity accumulation in the core. Higher gas puff… read more here.

DOI: 10.1093/mnras/stab394
Abstract: We study the gravitationally-dominated, accretion-driven evolution of a prestellar core. In our model, as the core's density increases, it remains immersed in a constant-density environment and so it accretes from this environment, increasing its mass… read more here.
