Global MHD simulations of the solar convective zone using a volleyball mesh decomposition. I. Pilot
Andrius Popovas, Åke Nordlund, Mikolaj Szydlarski
Solar modelling has long been split into ''internal'' and ''surface'' modelling, because of the lack of tools to connect the very different scales in space and time, as well as the…
The Dynamical State of Massive Clumps
Zu-Jia Lu, Veli-Matti Pelkonen, Mika Juvela +3
The dynamical state of massive clumps is key to our understanding of the formation of massive stars. In this work, we study the kinematic properties of massive clumps using synthet…
Physical Properties and Real Nature of Massive Clumps in the Galaxy
Zu-Jia Lu, Veli-Matti Pelkonen, Mika Juvela +3
Systematic surveys of massive clumps have been carried out to study the conditions leading to the formation of massive stars. These clumps are typically at large distances and unre…
A simple and efficient solver for self-gravity in the DISPATCH astrophysical simulation framework
J. P. Ramsey, T. Haugbølle, Å. Nordlund
We describe a simple and effective algorithm for solving Poisson's equation in the context of self-gravity within the DISPATCH astrophysical fluid framework. The algorithm leverage…
Microscopic Processes in Global Relativistic Jets Containing Helical Magnetic Fields: Dependence on Jet Radius
Ken-Ichi Nishikawa, Yosuke Mizuno, Jose L. Gomez +12
In this study we investigate jet interaction at a microscopic level in a cosmological environment, which responds to a key open question in the study of relativistic jets. Using sm…
Microscopic Processes in Global Relativistic Jets Containing Helical Magnetic Fields
Ken-Ichi Nishikawa, Yosuke Mizuno, Jacek Niemiec +11
In the study of relativistic jets one of the key open questions is their interaction with the environment on the microscopic level. Here, we study the initial evolution of both ele…
