Far-IR and radio thermal continua in solar flares

open access: yes, 2009
With the invention of new far-infrared (FIR) and radio mm and sub-mm instruments (DESIR on SMESE satellite, ESO-ALMA), there is a growing interest in observations and analysis of solar flares in this so far unexplored wavelength region. Two principal radiation mechanisms play a role: the synchrotron emission due to accelerated particle beams moving in ...

Characteristics of gamma-ray line flares [PDF]

open access: yes
Observations of solar gamma rays by the Solar Maximum Mission (SMM) demonstrate that energetic protons and ions are rapidly accelerated during the impulsive phase.

Flare stars at radio wavelengths [PDF]

open access: yes
The radio emission from dMe flare stars is discussed using Very Large Array and Arecibo observations as examples. Active flare stars emit weak, unpolarized, quiescent radio radiation that may be always present.

Solar Type J Radio Bursts and the Associated Coronal Loop

open access: yesThe Astrophysical Journal
The solar type J radio burst is a variant of type III bursts, which are a probe for understanding solar energetic electrons and local electron density. This study investigates a type J burst event on 2017 September 9.

X-Ray/Radio Quasiperiodic Pulsations Associated with Plasmoids in Solar Flare Current Sheets

open access: yesThe Astrophysical Journal
Plasmoids (or magnetic islands) are believed to play an important role in the onset of fast magnetic reconnection and particle acceleration during solar flares and eruptions.

Estimating the Total Energy Content in Escaping Accelerated Solar Electron Beams

open access: yesThe Astrophysical Journal
Quantifying the energy content of accelerated electron beams during solar eruptive events is a key outstanding objective that must be constrained to refine particle acceleration models and understand the electron component of space weather.

VLA-Max '91 tests of high energy flare physics [PDF]

open access: yes
The potential for the Very Large Array (VLA) contributions during the coming maximum in solar activity is illustrated by unpublished observations of solar flares on 28 May, 8 June, 24 June, and 30 September 1988.

Measuring the Magnetic Field of a Coronal Mass Ejection from the Low to Middle Corona

open access: yesThe Astrophysical Journal Letters
A major challenge in understanding the initiation and evolution of coronal mass ejections (CMEs) is measuring the magnetic field of the magnetic flux ropes (MFRs) that drive CMEs.
