A comparative study of solar flux emergence and eruptivity in simulations of horizontal versus toroidal magnetic fields

Vaggelis Karantanis, Juxhin Zhuleku, Vasilis Archontis +1

Context: Magnetic flux emergence is a fundamental driver of eruptive activity in the solar atmosphere. While many numerical studies employed idealized horizontal flux tubes, toroid…

Observations of microwave emission from solar jets and comparison with MHD simulations

Costas E. Alissandrakis, Vasilis Archontis, Kostas Moraitis

We computed the thermal microwave emission from a 3D magnetohydrodynamic (MHD) simulation and compared it with observations of solar jets. The simulation treats the emergence of ma…

Magnetic flux cancellation in a flux-emergence magnetohydrodynamics simulation of coronal hole eruptions and jets

Spiros Patsourakos, Vasilis Archontis

We search for signatures of magnetic flux cancellation in a 3D resistive MHD flux-emergence simulation of coronal jets and eruptions in a coronal-hole-like environment. To do this,…

Recurrent eruptions from the emergence of a toroidal flux tube

J. Zhuleku, V. Archontis, K. Moraitis

Solar eruptive behavior is often modeled with magnetohydrodynamic simulations of magnetic flux emergence. The usual geometry considered is that of a horizontal cylindrical magnetic…

Magnetic flux emergence and solar eruptions in partially ionized plasmas

Georgios Chouliaras, V. Archontis

We have performed 3D MHD simulations to study the effect of partial ionization in the process of magnetic flux emergence in the Sun. In fact, we continue previous work and we now f…
