New Estimate for the Cosmic Ray-Induced Photodissociation Rate in the Interstellar Medium
O. Sipilä, P. Caselli, M. Padovani +5
In the interstellar medium, cosmic rays (CRs) generate a field of ultraviolet (UV) photons via the excitation and subsequent radiative decay of molecules. This UV field i…

Formation of protostars and the launching of stellar core outflows with moving-mesh radiation non-ideal magnetohydrodynamics
Alexander C. Mayer, Rüdiger Pakmor, Thorsten Naab +5
We present an implementation of radiative transfer with flux-limited diffusion (FLD) for the moving-mesh code {\small AREPO} and use the method in a physical model for the formatio…

Protostellar disks in their natural habitat -- the formation of protostars and their accretion disks in the turbulent and magnetized interstellar medium
Alexander C. Mayer, Thorsten Naab, Paola Caselli +6
We present simulations of the supernova-driven turbulent interstellar medium (ISM) in a simulation domain of volume within which we resolve the formation of pro…
