Radiation-magnetohydrodynamics with MPI-AMRVAC using flux-limited diffusion
Nishant Narechania, Rony Keppens, Asif ud-Doula +2
Context. Radiation plays a significant role in solar and astrophysical environments as it may constitute a sizeable fraction of the energy density, momentum flux, and the total pre…

Suppression of photospheric velocity fluctuations in strongly magnetic O-stars in radiation-magnetohydrodynamic simulations
A. ud-Doula, J. O. Sundqvist, N. Narechania +3
O-stars generally show clear signs of strong line-broadening (in addition to rotational broadening) in their photospheric absorption lines (typically referred to as 'macroturbulenc…
