Non-ideal MHD simulations of subcritical prestellar cores with non-equilibrium chemistry

Aris Tritsis, Christoph Federrath, Karen Willacy +1

Non-ideal magnetohydrodynamic (MHD) effects are thought to be gravity's closest ally in overcoming the support of magnetic fields and in forming stars. Here, we modify the publicly…

Dynamo effect in unstirred self-gravitating turbulence

Axel Brandenburg, Evangelia Ntormousi

In many astrophysical environments, self-gravity can generate kinetic energy, which, in principle, is available for driving dynamo action. Using direct numerical simulations, we sh…
