Difference in the heliospheric modulation of cosmic-ray protons and electrons during the solar minimum period of 2006 to 2009
(EDP Sciences, 2017)Context. The PAMELA experiment observed galactic proton and electron spectra down to 70 MV and 400 MV, respectively, from mid-2006 to the end of 2009 during what is called an A < 0 solar magnetic polarity cycle. During ... -
Energy spectra of carbon and oxygen with HELIOS E6: radial gradients of anomalous cosmic ray oxygen within 1 AU
(EDP Sciences, 2018)Context. Anomalous cosmic rays (ACRs) are well-suited to probe the transport conditions of cosmic rays in the inner heliosphere.We revisit the HELIOS data not only in view of the upcoming Solar Orbiter experiment but also ... -
Latitudinal gradients of galactic cosmic rays during the 2007 solar minimum
(IOP Publishing, 2008)Ulysses, launched in 1990 October in the maximum phase of solar cycle 22, completed its third out-of-ecliptic orbit in 2008 February. This provides a unique opportunity to study the propagation of cosmic rays over a wide ...
