Secondary Antiprotons and Propagation of Cosmic Rays in the Galaxy and Heliosphere
Igor V. Moskalenko,Igor V. Moskalenko,Andrew W. Strong,Jonathan F. Ormes,Marius S. Potgieter +4 more
TL;DR: In this article, the authors used the propagation code GALPROP to calculate interstellar cosmic-ray propagation for a variety of models and showed that there is no simple model capable of accurately describing the whole variety of data: boron/carbon and sub-iron/iron ratios, spectra of protons, helium, antiprotons, positrons, electrons, and diUuse c-rays.

The Nonpotentiality of Active-Region Coronae and the Dynamics of the Photospheric Magnetic Field
TL;DR: In this article, the authors compare TRACE EUV images of active-region coronae and potential-field source-surface extrapolations based on SOHO MDI magnetograms for 95 active regions.

What Is Missing from Our Understanding of Long-Term Solar and Heliospheric Activity?
TL;DR: In this article, the authors simulate the evolution of the magnetic field at the solar surface and in the heliosphere during the last 340 yr using a state-of-the-art model.

TL;DR: The BESS-Polar spectrometer had its first successful balloon flight over Antarctica in December 2004, and during the 8.5-day long-duration flight, almost 0.9 billion events were recorded and 1,520 antiprotons were detected in the energy range 0.1 − 4.2 GeV as mentioned in this paper.
Journal ArticleDOI
Solar cycle variation in the heliosphere
TL;DR: For over three decades a succession of spacecraft have provided in situ measurements of interplanetary plasma and magnetic field parameters as discussed by the authors, and these measurements span a range of heliocentric distances from 0.3 to 61 AU, and provide an explicit picture of the three-dimensional structure of the inner and outer heliosphere.

On potential field models of the solar corona
Y. M. Wang,N. R. Sheeley +1 more
TL;DR: In this article, it is argued that the observed photospheric field should first be corrected for line-of-sight projection and then matched to the radial component of the potential field.
Journal ArticleDOI
Coronal holes and high-speed wind streams
TL;DR: In this article, the authors identified Bartel's M regions as sources of high-speed wind streams that produce recurrent geomagnetic variations in the solar corona and proposed a model for the birth and decay of coronal holes.
