Solar jets: SDO and IRIS observations in the perspective of new MHD simulations

B Schmieder - Frontiers in Astronomy and Space Sciences, 2022 - frontiersin.org
Solar jets are observed as collimated plasma beams over a large range of temperatures and
wavelengths. They have been observed in H α and optical lines for more than 50 years and …

Genesis and coronal-jet-generating eruption of a solar minifilament captured by IRIS slit-raster spectra

NK Panesar, SK Tiwari, RL Moore… - The Astrophysical …, 2022 - iopscience.iop.org
We present the first Mg ii slit-raster spectra from the Interface Region Imaging Spectrograph
(IRIS) that fully capture the genesis and coronal-jet-generating eruption of a central-disk …

Magnetic field amplification and structure formation by the Rayleigh-Taylor instability

BP Braileanu, VS Lukin, E Khomenko - Astronomy & Astrophysics, 2023 - aanda.org
We report our results from a set of high-resolution, two-fluid, non-linear simulations of the
magnetized Rayleigh Taylor instability (RTI) at the interface between a solar prominence …

Multiwavelength study of on-disk coronal-hole jets with IRIS and SDO observations

M Koletti, C Gontikakis, S Patsourakos… - Astronomy & …, 2024 - aanda.org
Context. Solar jets are an important field of study, as they may contribute to the mass and
energy transfer from the lower to the upper atmosphere. Aims. We use the Interface Region …

Two-fluid reconnection jets in a gravitationally stratified atmosphere

BP Braileanu, R Keppens - Astronomy & Astrophysics, 2023 - aanda.org
Context. Density decreases exponentially with height in the gravitationally stratified solar
atmosphere, and therefore collisional coupling between the ionized plasma and the neutrals …

Numerical studies of magnetic reconnection and heating mechanisms for the Ellerman bomb

M Liu, L Ni, GC Cheng, U Ziegler… - Research in Astronomy …, 2023 - iopscience.iop.org
Abstract An Ellerman Bomb (EB) is a kind of small scale reconnection event, which is
ubiquitously formed in the upper photosphere or the lower chromosphere. The low …

Solar Active Region Coronal Jets. III. Hidden-onset Jets

AC Sterling, RL Moore, NK Panesar - The Astrophysical Journal, 2024 - iopscience.iop.org
Solar quiet-and coronal-hole region coronal jets frequently clearly originate from erupting
minifilaments, but active-region jets often lack an obvious erupting-minifilament source. We …

Interaction of solar jets with filaments: Triggering of large-amplitude filament oscillations

R Joshi, M Luna, B Schmieder… - Astronomy & …, 2023 - aanda.org
Context. Large-amplitude oscillations (LAOs) are often detected in filaments. Using multi-
wavelength observations, their origin can be traced back to the interaction with eruptions …

Magnetic helicity and energy budgets of jet events from an emerging solar active region

A Nindos, S Patsourakos, K Moraitis… - Astronomy & …, 2024 - aanda.org
Using photospheric vector magnetograms obtained by the Helioseismic and Magnetic
Imager onboard the Solar Dynamics Observatory and a magnetic connectivity-based …

Two-sided Loop Solar Jet Driven by the Eruption of a Small Filament in a Big Filament Channel

J Yang, H Chen, J Hong, B Yang… - The Astrophysical …, 2024 - iopscience.iop.org
Similar to the cases of anemone jets, two-sided loop solar jets can also be produced by
either flux emergence from the solar interior or small-scale filament eruptions. Using high …
