Magnetically threaded accretion disks in resistive magnetohydrodynamic simulations and asymptotic expansion
Miljenko Čemeljić, Włodek Kluźniak, Varadarajan Parthasarathy
Aims. A realistic model of magnetic linkage between a central object and its accretion disk is a prerequisite for understanding the spin history of stars and stellar remnants. To t…
A magnetized thin accretion disk: numerical simulations compared with asymptotic expansion
M. Čemeljić, W. Kluźniak, V. Parthasarathy
To obtain a simple description of a geometrically thin magnetic accretion disk, we apply the method of asymptotic expansion. For the first time we write a full set of stationary as…
Analytical solution for magnetized thin accretion disk in comparison with numerical simulations
Miljenko Čemeljić, Varadarajan Parthasarathy, Włodek Kluźniak
We obtained equations for a thin magnetic accretion disk, using the method of asymptotic approximation. They cannot be solved analytically-without solutions for a magnetic field in…
