Wave excitation by a collapsing granule: insights from IFU observations and high-resolution RMHD simulations
J. Buttler, G. Vigeesh, I. Milić +5
Context. Granular collapse is an ubiquitous process of granular evolution on the solar surface, but it is hard to analyze in sufficient spatial, temporal, and spectral detail. Aims…
An innovative and automated method for vortex identification. I. Description of the SWIRL algorithm
José Roberto Canivete Cuissa, Oskar Steiner
Context. A universally accepted definition of what a vortex is has not yet been reached. Therefore, we lack an unambiguous and rigorous method for the identification of vortices in…
Methodology for estimating the magnetic Prandtl number and application to solar surface small-scale dynamo simulations
Fabio Riva, Oskar Steiner
Context. A crucial step in the numerical investigation of small-scale dynamos in the solar atmosphere consists of an accurate determination of the magnetic Prandtl number, Prm, ste…
A novel fourth-order WENO interpolation technique. A possible new tool designed for radiative transfer
Gioele Janett, Oskar Steiner, Ernest Alsina Ballester +2
Context. Several numerical problems require the interpolation of discrete data that present various types of discontinuities. The radiative transfer is a typical example of such a…
The Alfvénic nature of chromospheric swirls
Andrea Francesco Battaglia, José Roberto Canivete Cuissa, Flavio Calvo +2
We investigate the evolution and origin of small-scale chromospheric swirls by analyzing numerical simulations of the quiet solar atmosphere, using the radiative magnetohydrodynami…
On the effect of oscillatory phenomena on Stokes inversion results
P. H. Keys, O. Steiner, G. Vigeesh
Stokes inversion codes are crucial in returning properties of the solar atmosphere, such as temperature and magnetic field strength. However, the success of such algorithms to retu…
