Context. Nanoflares are impulsive energy releases that occur due to magnetic reconnection
in the braided coronal magnetic field, which is a potential mechanism for heating the corona …

It is largely agreed that many coronal loops—those observed at a temperature of about 1 MK—
are bundles of unresolved strands that are heated by storms of impulsive nanoflares. The …

All theoretical models of nanoflare heating in the solar corona predict loops with an
unresolved multistrand structure, which is in discrepancy with the quasi-isothermal cross …

Context. Magnetic energy is required to heat the corona, the outer atmosphere of the Sun, to
millions of degrees. Aims. We study the nature of the magnetic energy source that is …

To evaluate the usefulness of spectroscopic techniques for diagnosing realistic solar
plasmas and to better understand the physical origin of coronal heating, we have simulated …

Fine-scale braiding of coronal magnetic loops by continuous footpoint motions may power
coronal heating via nanoflares, which are spontaneous fine-scale bursts of internal …

The radiative signatures of the nanoflare model for coronal heating are investigated. If an
observed coronal loop is assumed to consist of many small strands that cannot be …

ABSTRACT A nanoflare-heated coronal loop model is developed based on the model of
Vekstein & Katsukawa. We performed numerical simulations based on the model, and then …

Solar flares are intense bursts of electromagnetic radiation accompanied by energetic
particles and hard X-rays. They occur when magnetic flux loops erupt in the solar …

Impulsive nanoflares are expected to transiently heat the plasma confined in coronal loops
to temperatures of the order of 10 MK. Such hot plasma is hardly detected in quiet and active …
