Modulation of galactic cosmic ray protons and electrons during an unusual solar minimum
(IOP Publishing, 2009)
During the latest Ulysses out-of-ecliptic orbit the solar wind density, pressure, and magnetic field strength have been the lowest ever observed in the history of space exploration. Since cosmic ray particles respond to ...
Cosmic ray modulation with a Fisk-type heliospheric magnetic field and a latitude-dependent solar wind speed
(Elsevier, 2009)
The effect of a latitude-dependent solar wind speed on a Fisk heliospheric magnetic field [Fisk, L. A. Motion of the footpoints of heliospheric magnetic field lines at the Sun: implications for recurrent energetic particle ...
Cosmic rays in the dynamic heliosphere
(Japan Society of Plasma Science and Nuclear Fusion Research, 2009)
he relation between the dynamics of the heliosphere,
its shape and geometry, so
lar activity and cosmic ray
variations is addressed. The global features of the helio
sphere influence what happens
inside its boundaries ...
Probing the ATIC peak in the cosmic-ray electron spectrum with H.E.S.S.
(EDP Sciences, 2009)
The measurement of an excess in the cosmic-ray electron spectrum between 300 and 800 GeV by the ATIC experiment has – together with
the PAMELA detection of a rise in the positron fraction up to
≈
100 GeV – ...
