MeV/nucleon 0010 and above/ A9660R Solar flares, bursts, and related phenomena A9660V Solar particle radiation, solar windThe influence of Coulomb collisions in two-component plasma on the nuclear composition and the charge-state of accelerated particles is investigated. The main characteristics are...
Plastic and glass track detectors on rockets and Apollo spacecraft have been used to determine the composition of particles from He to Ni at energies from 0.1 to 50 MeV per nucleon in several solar flares of widely varying intensities. At low energies the composition of solar particles is enric...
The Sun's surface is made up of a very hot, ionized gas called plasma. Plasma is found both on the Sun's surface and the Sun's interior layers. What is the Sun Made Of? The Sun is a very important part of our lives on planet Earth, along with the entire solar system. The Sun...
The main result obtained is that the long-term average neon isotopic composition in solar flares has a value of Ne-20/Ne-22 = ll.6iQ.2 which is different from the solar wind ratio of 13.6 by Geiss group (3). These results bear importantly on the acceleration mechanism in solar flares....

Unexpected inhomogeneityClouds of pristine gas (magenta) accrete onto the Milky Way but do not efficiently mix in the galactic disc, as highlighted for the solar neighbourhood (zoom-in). (©Mark A Garlick) The interstellar medium (ISM) of gas and dust between the stars seems surprisingly pat...
Accelerated Particle Composition and Energetics and Ambient Abundances from Gamma-Ray Spectroscopy of the 1991 June 4 Solar Flare The Oriented Scintillation Spectrometer Experiment (OSSE) on board the Compton Gamma Ray Observatory observed the 1991 June 4 X12+ solar flare, one of the ......
As it crossed the disk, it produced 4 X-class flares and at least 3 halo coronal mass ejections. Two large SEP events were generated when the region was at ~E70 and ~W25 and were observed by several spacecraft, including ACE and STEREO. We have combined observations from the Solar ...
For example, during solar flares, both electromagnetic radiation and cosmic rays are emitted [11]. Their coordinated signals reveal important information that aids researchers in identifying their source. As the energy increases, the flux of cosmic rays decreases rapidly (Figure 1), where the flux ...
Solar physics, astrophysics and astronomy (flares and mass ejectionsBased on elemental abundance ratios derived from the Ulysses COSPIN/LET measurements, we classified the energetic particle populations during and after the socalled Fast Latitude Scan – the time period during which the Ulysses space...
